AB  - Sintetizovali smo seriju Ni kompleksa koristeći različite donorske ligande na bazi NNO 
hidrazona i azidne anjone. Tri kompleksa su kristalizovala kao dvonuklearna, Ni(II) jona 
su koordinovani sa NNO ligandom i tri azidna liganda (dva mostna). U četvrtom 
kompleksu, Ni (II) je koordinovan sa dva NNO liganda. Da bismo razumeli ove različite 
ishode, izračunali smo ∆G energije za dimerizaciju i formiranje kompleksa sa dva NNO 
liganda, iz mononuklearnih kompleksa. Energije su izračunate koristeći M06-2X metodu 
sa Grimeovom D3 disperzionom korekcijom i def2-TZVP bazisom. Iako je dimerizacija 
povoljnija u svim slučajevima, ∆G energetska razlika je samo 1,7 kcal/mol za četvrti 
kompleks. Ova mala razlika se može prevazići energijama interakcije sa rastvorom ili u 
kristalnim strukturama. ∆G energetske razlike u drugim kompleksima su od 5 kcal/mol do 
15 kcal/mol.
AB  - We have synthesized a series of a Ni complex using different NNO hydrazone-based donor 
ligands and azide anions. Three complexes crystallized as dinuclear, Ni(II) ions are 
coordinated with NNO ligand and three azide ligands (two bridging). In the fourth 
complex, Ni(II) is coordinated with two NNO ligands. To understand these different 
outcomes, we calculated the ∆G energies for dimerization and formation of complexes 
with two NNO ligands, from mononuclear complexes. The energies are calculated using 
the M06-2X method with Grimmes D3 dispersion correction and def2-TZVP basis. Aldo 
the dimerization is more favorable in all cases, the ∆G energy difference is only 1.7 
kcal/mole for the fourth complex. This small difference could be overcome by the 
interaction energies with the solution or in the crystal structures. The ∆G energy 
differences in other complexes are from 5 kcal/mol to 15 kcal/mol.

AB  - Лиганд HLCl (E)-2-(2-(1-(6-бромпиридин-2-ил)етилиден)хидразинил)-N,N,N-триметил-2-оксоетан-1-аминиум хлорид је добијен у реакцији 2-ацетил-6-бромопиридина и Жираровог Т реагенса у метанолу. Комплекс 1, октаедарске геометрије састоји се од два координована молекула лиганда, опште формуле [ZnL2](BF4)2. Добијен је у реакцији лиганда HLCl са Zn(BF4)2·6H2O и NaN3 у молском односу 1:1:4, док је као растварач коришћена смеша метанола и воде. Комплекс 2 састава [ZnL(NCO)2], где је Zn(II) пентакоординован преко једног молекула лиганда и два лиганда NCO–, са искривљеном тригонално бипирамидалном геометријом, добијен је у истим реакционим условима као и комплекс 1 (смеша растварача МeOH/H2O и молски однос 1:1:4). Међутим, у реакцији лиганда HLCl са Zn(BF4)2·6H2O и NaN3 у великом вишку (молски однос 1:1:12) у истој смеши растварача као у претходним реакцијама добијен је мононуклеарни Zn(II) комплекс 3, састава [ZnL(N3)2]. Укратко, повећана количина азида доводи до формирања комплекса 3, у коме је један лиганд координован за централни метални атом у депротонованом облику док преостала два места заузимају азиди. Комплекс 1 [ZnL2](BF4)2, кристалише у орторомбичној просторној групи Pbcn са једним комплексним катјоном [ZnL2]2+ и два BF4– анјона. Комплекси 2 ([ZnL(NCO)2]) и 3 ([ZnL(N3)2]) кристалишу у триклиничној P-1 просторној групи са једним молекулом по асиметричној јединици.
AB  - The condensation of 2-acetyl-6-bromopyridine with Girard's T reagent in methanol produced the ligand HLCl (E)-2-(2-(1-(6-bromopyridin-2-yl)ethylidene)hydrazinyl)-N,N,N-trimethyl-2-oxoethan-1-aminium chloride. Com-plex 1, an octahedral complex containing two molecules of the coordinated ligand [ZnL2](BF4)2, was obtained when the ligand HLCl reacted with Zn(BF4)2·6H2O and NaN3 in molar ratio 1:1:4 in a solvent mixture of water and methanol. Complex 2, with the composition [ZnL(NCO)2], was obtained under the same reaction condi-tions as complex 1 (solvent mixture MeOH/H2O and molar ratio 1:1:4). Zn(II) is pentacoordinated via one ligand molecule and two NCO– ligands, with a distorted trigonal bipyramidal geometry. However, by reacting HLCl with Zn(BF4)2·6H2O and NaN3 in excess (1:1:12) in the same solvent mixture as in the previous reac-tions the mononuclear Zn(II) complex 3, with the composition [ZnL(N3)2], was formed. In short, increasing the amount of azide leads to forming 3, where one deprotonated ligand and two azide ligands are coordinated to Zn(II). Complex 1, [ZnL2](BF4)2, crystallized in orthorhombic Pbcn space group as one independent complex cation [ZnL2]2+ and two BF4– anions. Complexes 2 ([ZnL(NCO)2]) and 3 ([ZnL(N3)2]) both crystallize as independent molecules in the asymmetric unit of the triclinic P–1 space group.

AB  - This talk will present our efforts to understand and control metal-ligand bonding based on density functional calculations, including Energy Decomposition Analysis and the Quantum Theory of Atoms in Molecules. The talk will focus on the intricacies of interactions involving weakly coordinated anions such as BF4−, NO3− and ClO4−. These anions are often considered as counterions and only spectators. We will try to answer these questions: Do they interact directly with the metal ion? When do they interact? Is the traditional geometric interpretation sufficient to address these issues? We will show how seemingly inert anions can influence the electronic structure and stability of transition metal complexes.

AB  - In this paper, three different Zn(II) complexes with (E)-2-(2-(1-(6-bromopyridin-2-yl)ethylidene)hydrazinyl)-N,N,N-trimethyl-2-oxoethan-1-aminium chloride (HLCl) have been synthesized and characterized by single crystal X-ray diffraction, elemental analysis, IR and NMR spectroscopy. All complexes are mononuclear, with the ligand (L) coordinated in a deprotonated formally neutral zwitterionic form via NNO donor set atoms. Complex 1 forms an octahedral geometry with the composition [ZnL2](BF4)2, while complexes 2 [ZnL(NCO)2] and 3 [ZnL(N3)2] form penta-coordinated geometry. Density functional theory (DFT) calculations were performed to enhance our understanding of the structures of the synthesized complexes and the cytotoxic activity of the complexes was tested against five human cancer cell lines (HeLa, A549, MDA-MB-231, K562, LS 174T) and normal human fibroblasts MRC-5. Additionally, antimicrobial and antifungal activity of these complexes was tested against a panel of Gram-negative and Gram-positive bacteria, two fungal strains, and a yeast strain. It is noteworthy that all three complexes show selective antifungal activity comparable to that of amphotericin B. Molecular docking analysis predicted that geranylgeranyl pyrophosphate synthase, an enzyme essential for sterol biosynthesis is the most likely target for inhibition by the tested complexes.

AB  - This talk will present our efforts to understand and control metal-ligand bonding based on density functional calculations, including Energy Decomposition Analysis and the Quantum Theory of Atoms in Molecules. The talk will focus on the intricacies of interactions involving weakly coordinated anions such as BF4−, NO3− and ClO4−. These anions are often considered as counterions and only spectators. We will try to answer these questions: Do they interact directly with the metal ion? When do they interact? Is the traditional geometric interpretation sufficient 
to address these issues? We will show how seemingly inert anions can influence the electronic structure and stability of transition metal complexes.

AB  - Sintetizovali smo seriju Ni kompleksa koristeći različite donorske ligande na bazi NNO hidrazona i azidne anjone. Tri kompleksa su kristalizovala kao dvonuklearna, Ni(II) jona su koordinovani sa NNO ligandom i tri azidna liganda (dva mostna). U četvrtom kompleksu, Ni (II) je koordinovan sa dva NNO liganda. Da bismo razumeli ove različite ishode, izračunali smo ΔG energije za dimerizaciju i formiranje kompleksa sa dva NNO liganda, iz mononuklearnih kompleksa. Energije su izračunate koristeći M06-2X metodu sa Grimeovom D3 disperzionom korekcijom i def2-TZVP bazisom. Iako je dimerizacija povoljnija u svim slučajevima, ΔG energetska razlika je samo 1,7 kcal/mol za četvrti kompleks. Ova mala razlika se može prevazići energijama interakcije sa rastvorom ili u kristalnim strukturama. ΔG energetske razlike u drugim kompleksima su od 5 kcal/mol do 15 kcal/mol.
AB  - We have synthesized a series of a Ni complex using different NNO hydrazone-based donor ligands and azide anions. Three complexes crystallized as dinuclear, Ni(II) ions are coordinated with NNO ligand and three azide ligands (two bridging). In the fourth complex, Ni(II) is coordinated with two NNO ligands. To understand these different outcomes, we calculated the ΔG energies for dimerization and formation of complexes with two NNO ligands, from mononuclear complexes. The energies are calculated using the M06-2X method with Grimmes D3 dispersion correction and def2-TZVP basis. Aldo the dimerization is more favorable in all cases, the ΔG energy difference is only 1.7 kcal/mole for the fourth complex. This small difference could be overcome by the interaction energies with the solution or in the crystal structures. The ΔG energy differences in other complexes are from 5 kcal/mol to 15 kcal/mol.

AB  - The condensation of 2-acetyl-6-bromopyridine with Girard's T reagent in methanol produced the ligand HLCl (E)-2-(2-(1-(6-bromopyridin-2-yl)ethylidene)hydrazinyl)-N,N,N-trimethyl-2-oxoethan-1-aminium chloride. Com-plex 1, an octahedral complex containing two molecules of the coordinated ligand [ZnL2](BF4)2, was obtained when the ligand HLCl reacted with Zn(BF4)2·6H2O and NaN3 in molar ratio 1:1:4 in a solvent mixture of water and methanol. Complex 2, with the composition [ZnL(NCO)2], was obtained under the same reaction condi-tions as complex 1 (solvent mixture MeOH/H2O and molar ratio 1:1:4). Zn(II) is pentacoordinated via one ligand molecule and two NCO– ligands, with a distorted trigonal bipyramidal geometry. However, by reacting HLCl with Zn(BF4)2·6H2O and NaN3 in excess (1:1:12) in the same solvent mixture as in the previous reac-tions the mononuclear Zn(II) complex 3, with the composition [ZnL(N3)2], was formed. In short, increasing the amount of azide leads to forming 3, where one deprotonated ligand and two azide ligands are coordinated to Zn(II). Complex 1, [ZnL2](BF4)2, crystallized in orthorhombic Pbcn space group as one independent complex cation [ZnL2]2+ and two BF4– anions. Complexes 2 ([ZnL(NCO)2]) and 3 ([ZnL(N3)2]) both crystallize as independent molecules in the asymmetric unit of the triclinic P–1 space group.
AB  - Лиганд HLCl (E)-2-(2-(1-(6-бромпиридин-2-ил)етилиден)хидразинил)-N,N,N-триметил-2-оксоетан-1-аминиум хлорид је добијен у реакцији 2-ацетил-6-бромопиридина и Жираровог Т реагенса у метанолу. Комплекс 1, октаедарске геометрије састоји се од два координована молекула лиганда, опште формуле [ZnL2](BF4)2. Добијен је у реакцији лиганда HLCl са Zn(BF4)2·6H2O и NaN3 у молском односу 1:1:4, док је као растварач коришћена смеша метанола и воде. Комплекс 2 састава [ZnL(NCO)2], где је Zn(II) пентакоординован преко једног молекула лиганда и два лиганда NCO–, са искривљеном тригонално бипирамидалном геометријом, добијен је у истим реакционим условима као и комплекс 1 (смеша растварача МeOH/H2O и молски однос 1:1:4).

abstract = "The condensation of 2-acetyl-6-bromopyridine with Girard's T reagent in methanol produced the ligand HLCl (E)-2-(2-(1-(6-bromopyridin-2-yl)ethylidene)hydrazinyl)-N,N,N-trimethyl-2-oxoethan-1-aminium chloride. Com-plex 1, an octahedral complex containing two molecules of the coordinated ligand [ZnL2](BF4)2, was obtained when the ligand HLCl reacted with Zn(BF4)2·6H2O and NaN3 in molar ratio 1:1:4 in a solvent mixture of water and methanol. Complex 2, with the composition [ZnL(NCO)2], was obtained under the same reaction condi-tions as complex 1 (solvent mixture MeOH/H2O and molar ratio 1:1:4). Zn(II) is pentacoordinated via one ligand molecule and two NCO– ligands, with a distorted trigonal bipyramidal geometry. However, by reacting HLCl with Zn(BF4)2·6H2O and NaN3 in excess (1:1:12) in the same solvent mixture as in the previous reac-tions the mononuclear Zn(II) complex 3, with the composition [ZnL(N3)2], was formed. In short, increasing the amount of azide leads to forming 3, where one deprotonated ligand and two azide ligands are coordinated to Zn(II). Complex 1, [ZnL2](BF4)2, crystallized in orthorhombic Pbcn space group as one independent complex cation [ZnL2]2+ and two BF4– anions. Complexes 2 ([ZnL(NCO)2]) and 3 ([ZnL(N3)2]) both crystallize as independent molecules in the asymmetric unit of the triclinic P–1 space group., Лиганд HLCl (E)-2-(2-(1-(6-бромпиридин-2-ил)етилиден)хидразинил)-N,N,N-триметил-2-оксоетан-1-аминиум хлорид је добијен у реакцији 2-ацетил-6-бромопиридина и Жираровог Т реагенса у метанолу. Комплекс 1, октаедарске геометрије састоји се од два координована молекула лиганда, опште формуле [ZnL2](BF4)2. Добијен је у реакцији лиганда HLCl са Zn(BF4)2·6H2O и NaN3 у молском односу 1:1:4, док је као растварач коришћена смеша метанола и воде. Комплекс 2 састава [ZnL(NCO)2], где је Zn(II) пентакоординован преко једног молекула лиганда и два лиганда NCO–, са искривљеном тригонално бипирамидалном геометријом, добијен је у истим реакционим условима као и комплекс 1 (смеша растварача МeOH/H2O и молски однос 1:1:4). Међутим, у реакцији лиганда HLCl са Zn(BF4)2·6H2O и NaN3 у великом вишку (молски однос 1:1:12) у истој смеши растварача као у претходним реакцијама добијен је мононуклеарни Zn(II) комплекс 3, састава [ZnL(N3)2].

AB  - Hemiacetals of cyclopropanone can be isolated and stocked, contrary to their highly reactive parent ketone.  However, they are not readily converted to cyclopropanone, which limits their use as its synthetic equivalents.  2,2,2-trifluoroethoxy hemiacetals are expected to be better cyclopropanone surrogates, however, they have  never been prepared, so far. We show that oxyallyl cations with a heteroatom in the -position can be  intercepted with 2,2,2-trifluoroethanol, with formation of cyclopropanone trifluoroethoxy hemiacetals stable  enough to be isolated, purified and characterized. These species can serve as synthetic equivalents of  cyclopropanone under mild conditions.

AB  - Three new Zn(II) complexes with (E)-2-(2-(1-(6-bromopyridin-2-yl)ethylidene)hydrazinyl)-N,N,N-trimethyl-2-oxoethan-1-aminium chloride (HLCl) have been synthesized and characterized in the solid state and in solution by different methods. Complex 1 forms an octahedral geometry, while complexes 2 and 3 form distorted trigonal bipyramidal geometry. The biological activity of these complexes was tested against a panel of Gram-negative and Gram-positive bacteria, two fungal strains, and a yeast strain. Molecular docking analysis predicted that geranylgeranyl pyrophosphate synthase, an enzyme essential for sterol biosynthesis is the most likely target for inhibition by the tested complexes.

Elektronska struktura molekula primarno određuje sve njegove osobine. U slučaju kompleksa prelaznih metala, elektronska struktura zavisi od broja, geometrije i karaktera mezal-ligand veza. Potrebno je razumeti veliki broj mogućih uticaja, kao što su uticaj koordinacionog broja, simetrije, jačine ligandnog polja, spin-orbitalne sprege, spinskog i oksidacionog stanja, redoks potencijala, lokalizacije naelektrisanja i spina, elektronske degeneracije, itd. Konačno, potpuno razumevanje elektronske struktura kompleksa zahteva istraživanja koja prevazilaze samo osnovna elektronska stanja, tj. razmatranje i ekscitovanih stanja [4]. U ovom predavanju će biti predstavljeni naši napori u razumevanju i kontroli metal-ligand veza na osnovu proračuna zasnovanih na teoriji funkcionalne gustine (DFT).

AB  - A complete understanding of the electronic structure of transition metal complexes requires an
understanding of both the ground and excited states and their mutual influence. In addition, to get a complete picture, it is necessary to understand how the nuclei adapt upon electronic excitation. Thus, it is essential to go beyond a static understanding of molecular structure. The simplest computational approach is to study potential energy curves along specific reaction coordinates. Another practical approach is to use mixed quantum-classical non-adiabatic dynamics. Examples that will be discussed in this talk include mechanistic details of several fascinating phenomena in coordination chemistry - excited state linkage isomerization, excited state ligand dissociation, and excited state spin-state switching. It will be emphasized that understanding the role of excited states in transition metal complexes provides valuable insights into their properties and potential applications.

abstract = "A complete understanding of the electronic structure of transition metal complexes requires an
understanding of both the ground and excited states and their mutual influence. In addition, to get a complete picture, it is necessary to understand how the nuclei adapt upon electronic excitation. Thus, it is essential to go beyond a static understanding of molecular structure. The simplest computational approach is to study potential energy curves along specific reaction coordinates. Another practical approach is to use mixed quantum-classical non-adiabatic dynamics. Examples that will be discussed in this talk include mechanistic details of several fascinating phenomena in coordination chemistry - excited state linkage isomerization, excited state ligand dissociation, and excited state spin-state switching. It will be emphasized that understanding the role of excited states in transition metal complexes provides valuable insights into their properties and potential applications.",

AB  - Inspired by the emergence of resistance to currently available antifungal therapy and by the great potential of metal complexes for the treatment of various diseases, we synthesized three new silver(I) complexes containing clinically used antifungal azoles as ligands, [Ag(ecz)2]SbF6 (1, ecz is econazole), {[Ag(vcz)2]SbF6}n (2, vcz is voriconazole), and [Ag(ctz)2]SbF6 (3, ctz is clotrimazole), and investigated their antimicrobial properties. The synthesized complexes were characterized by mass spectrometry, IR, UV-vis and 1H NMR spectroscopy, cyclic voltammetry, and single-crystal X-ray diffraction analysis. In the mononuclear complexes 1 and 3 with ecz and ctz, respectively, the silver(I) ion has the expected linear geometry, in which the azoles are monodentately coordinated to this metal center through the N3 imidazole nitrogen atom. In contrast, the vcz-containing complex 2 has a polymeric structure in the solid state in which the silver(I) ions are coordinated by four nitrogen atoms in a distorted tetrahedral geometry. DFT calculations were done to predict the most favorable structures of the studied complexes in DMSO solution. All the studied silver(I) complexes have shown excellent antifungal and good to moderate antibacterial activities with minimal inhibitory concentration (MIC) values in the ranges of 0.01–27.1 and 2.61–47.9 μM on the selected panel of fungi and bacteria, respectively. Importantly, the complexes 1–3 have exhibited a significantly improved antifungal activity compared to the free azoles, with the most pronounced effect observed in the case of complex 2 compared to the parent vcz against Candida glabrata with an increase of activity by five orders of magnitude. Moreover, the silver(I)-azole complexes 2 and 3 significantly inhibited the formation of C. albicans hyphae and biofilms at the subinhibitory concentration of 50% MIC. To investigate the impact of the complex 3 more thoroughly on Candida pathogenesis, its effect on the adherence of C. albicans to A549 cells (human adenocarcinoma alveolar basal epithelial cells), as an initial step of the invasion of host cells, was studied.

AB  - Fe(III) and Mn(II) complexes with condensation product of thiosemicarbazide and 2-acetylthiazole (HL1, (E)-2-(1-(thiazol-2-yl)ethylidene)hydrazine-1-carbothioamide) have been synthesized and characterized by single-crystal X-ray diffraction, IR spectroscopy, and elemental analysis. In both complexes, the thiosemicarbazone ligand is coordinated in deprotonated form through the NNS donor set of atoms. However, while Fe(III) complex is in the doublet ground state with distorted octahedral geometry, the coordination environment around Mn(II) is distorted trigonal-prismatic, and the sextet state is found to be the ground state. DFT calculations were performed to rationalize spin state preferences, and continuous shape measure describes the deviation from ideal six-coordinated polyhedral geometries in the ground and excited states. Antimicrobial activity (against a panel of Gram-negative and Gram-positive bacteria, two yeast, and one fungal strain), brine shrimp assay, and DPPH radical scavenging activity of both complexes were evaluated, and these results relate to the electronic structure of the complexes.

AB  - During synthesis of Ni(II) complex with (E)−1-(2-oxo-2-(2-(1-(pyridin-2-
yl)ethylidene)hydrazinyl)ethyl)pyridin-1-ium ligand (L) unexpected oxidation of Ni(II) to Ni(III) with atmospheric oxygen occurred at mild conditions. Unusual spin and magnetic properties of the synthesized octahedral [NiL(N3)3] complex, were further investigated with Density Functional Theory (DFT) methods.

These complexes, together with four previously synthesised analogues, having hydrazone ligands with a NNO donor set of atoms, were successfully employed as catalysts in the ketone-amine-alkyne (KA2) coupling reaction, furnishing tetrasubstituted propargylamines, compounds with unique applications in organic chemistry. DFT calculations at the CAM-B3LYP/TZP level of theory were performed to elucidate the electronic structure of the investigated Zn(II) complexes, excellently correlating the structure of the complexes to their catalytic reactivity.

AB  - Mn(II) and Fe(III) complexes with condensation product of thiosemicarbazide and 2-acetylthiazole have been synthesized and characterized by single-crystal X-ray diffraction. Two complexes have the same ligand system – bis tridentate coordination of the thiosemicarbazone ligand through the NNS donor set of atoms. Furthermore, the central metal ions in both cases have the same d5
 electronic configuration. However, measured magnetism and analysis of the crystal geometries 
show that these two complexes have a different number of unpaired electrons. We 
rationalized the results by electronic structure calculations based on density functional 
theory. High-spin Mn(II) complex has trigonal-prismatic geometry with ionic metal-ligand bonding. Hund's rule of maximum multiplicity is responsible for its sextet spin-ground state. On the other hand, low-spin Fe(III) complex has octahedral coordination and strong metal-ligand covalency with delocalization of spin density toward ligands. Low-spin, doublet state is favored because of the nephelauxetic effect, i.e., smaller pairing energy in Fe(III) complex. Our results show that the difference in the electronic structure of the two complexes, i.e., different spin-ground states, directly affects these molecules' structure, magnetism, reactivity, and biological activities.

AB  - In the last two decades, considerable theoretical efforts have been made to develop  suitable methods for predicting and rationalizing the complicated electronic structure of  TM compounds. However, the matter remains open and calculations on molecules with  TM centers are still far from being straightforward. The main reason is that these  calculations require a balanced treatment of both static and dynamic correlations.  Furthermore, it is necessary to understand the influences of coordination number,  molecular symmetry, ligand field strength, spin-orbit coupling, spin and oxidation  states, redox potential, spin and charge localization, electronic degeneracies, etc.  Finally, a complete understanding of the electronic structure of TM compounds and  their properties requires investigations that go beyond the ground states alone, i.e., the  consideration of excited states.  In this talk we will present our efforts to understand and control metal-ligand bonding  based on density functional calculations, considering all its limitations. A fundamental  understanding of all factors influencing the properties of a molecule is inherently related  to its electronic structure. In the case of a transition metal (TM) complex, the electronic  structure is determined by the number, geometry, and character (e.g., σ-donating or π*- backdonating) of its metal-ligand bonds. In addition, a variety of examples will show  how experimental results and properties оf coordination compounds can be rationalized  using DFT calculations.
