AB  - The emerging threat of bacterial resistance to antibiotics prompts the urgent search for biomaterials for the treatment of infectious disease. Here we report on the synthesis and characterization of a multiphasic nanocomposite comprising magnetic iron oxide and silver nanoparticles. The method of synthesis involved the combustion of a metalorganic complex and reduction of the silver ions that were exchanged and/or adsorbed on the surface of iron oxide. Different physical and chemical treatments coupled to the reduction process, including ultrasound and Lugol's iodine solution, respectively, homogenized the distribution of the silver nanoparticles on the iron oxide phase. Remarkably, using ascorbic acid as a reductant enhanced the magnetic properties of the material as a result of the reduction of the magnetic matrix alongside the silver cations. The treatment with ultrasound detached large amounts of silver from the iron oxide phase and resulted in the lowest amount of silver incorporated in the nanocomposite. Despite that, this treatment led to the highest antibacterial activity against both Gram-positive and Gram-negative strains, indicating that the homogeneity of the distribution of silver on the iron oxide matrix is a more important determinant of the antibacterial performance than the amount of silver incorporated in the material. At the same time, the treatment with Lugol's iodine equally increased the distribution homogeneity, but induced excessive ion exchange and crystal lattice substitutions, thereby adversely affecting the antibacterial performance. This has indicated that the mode of binding silver to iron oxide can compensate for the positive effects of homogeneous distribution with respect to the antibacterial performance.

AB  - To investigate the magnetic behavior of starch-coated cobalt ferrites, well-established synthetic methods, i.e., coprecipitation, mechanochemical, ultrasonically assisted coprecipitation, microemulsion, and microwave-assisted hydrothermal syntheses were chosen for their preparation. The obtained materials had pure single-phase spinel structures. Scanning and transmission electron microscopy analyses revealed that the morphology of the samples is not uniform, and particle aggregation is a dominant process. Fourier transform infrared spectra and thermogravimetric analysis confirmed the presence of starch in all–coated samples. The unusually higher saturation magnetization of starch-coated samples than their as-prepared analogs, obtained by coprecipitation, ultrasonically assisted coprecipitation, and microwave-assisted hydrothermal methods, might be explained by the Ostwald ripening mechanism induced by the coating process. A decrease in magnetization was noticed for the starch-functionalized nanomaterials synthesized by mechanochemical and microemulsion methods, in comparison to their as-prepared analogs, i.e., the size distribution of such nanoparticles is narrow, and the average diameter of the grains is near critical for the Ostwald ripening process.

AB  - The light-transmitting measurements at the 655 nm wavelength were performed through starchcoated cobalt ferrite ferrofluids synthesized by well-established synthetic methods, i.e., coprecipitation, mechanochemical, ultrasonically assisted coprecipitation, microemulsion, and microwave-assisted hydrothermal syntheses, exposed to an external magnetic field of 200–400 mT. The investigated samples can be divided into the two groups. The first is where the samples showed higher rate of agglomeration and sedimentation effects. The group of samples synthesized by microemulsion, microwave-assisted hydrothermal method, and mechanochemical method showed less pronounced rate of chain formation. Such measurements present good method for the preliminary selection of possible magnetic resonance imaging (MRI) contrast agents between differently synthesized ferrite suspensions.

AB  - Hematite (α-Fe2O3) nanoparticles have been synthesized by thermal decomposition of iron(III)acetylacetonate precursor. The structure and morphology of the resulting powder  were investigated by X-ray powder diffraction (XRPD), Fourier transformation IR (FTIR),  scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS). Hematite-loading with silver was conducted using the reduction of silver nitrate by ascorbic acid realized by three different synthetic procedures – simple reduction process, ultrasonically supported reduction, and reduction after pre-treatment of hematite in Lugol's iodine. All synthesized hematite/silver samples were characterized withSEM, supported by EDS maps. Silver content was determined by Inductively Coupled Plasma Optical Emission spectroscopy (ICP-OES). The development of Ag-doped hematite nanocomposites, hetero-structures containing Ag and magnetic iron oxide,is indispensable in orderto take advantage of Ag containing nanocomposites in the field of biomedicine.

AB  - A simple organic-phase synthesis process was used to produce bare NiFe2O4 and ZnFe2O4 and core-shell ZnFe2O4@NiFe2O4 ferrite nanoparticles. X-ray powder diffractograms for all investigated powders show characteristic peaks of a spinel cubic structure without a secondary phase. Transmission electron microscopy (TEM) indicated the presence of nanoparticles that are smaller than 20 nm. The release of divalent ions (Ni2+ and Zn2+) from synthesized nanoparticles that were dispersed in saline solution, phosphate-buffered saline (PBS) and human serum, as determined by the inductively coupled plasma mass spectrometry (ICP-MS) method, was lower than 2 wt %. These results demonstrate the stability of the investigated nanoparticles in biologically relevant media and exclude the toxicity of Ni2+ and Zn2+ due to metal ion release, thereby opening a broad range of (bio)medical applications.

Obtained nanopowders were characterized by X-ray powder diffraction, Fourier transform IR analysis, scanning electron microscopy, and Energy-dispersive X-ray spectroscopy. X-ray powder diffraction confirmed the formation of high purity NiO and α-Fe2O3 crystal phases. In the case of α-Fe2O3, about five times larger average crystallite size was obtained. Fourier transform IR spectra of synthesized materials showed characteristic peaks for NiO and α-Fe2O3 nanostructures. To visualize the morphology and the chemical composition of the final products Scanning electron microscopy and Energy-dispersive X-ray spectroscopy were performed. The thermogravimetric analysis was done for a better understanding of the general thermal behavior of precursor compounds. This easy-to-perform and fast preparation method opens a broad range of obtained materials’ usage, particularly due to its economic viability.
AB  - У овом раду је први пут дата веома једноставна и брза синтеза наночестица никл-оксида (NiO) и хематита (α-Fe2O3) изведена у једном кораку термалном декомпозицијом аква комплекса прелазних метала чији је анјон камфор сулфонат. Добијени нано прахови су окарактерисани рендгенском дифракцијом на праху, ИЦ спектроскопијом, скенирајућом електронском микроскопијом и енергијски дисперзивном рендгенском спектроскопијом. Рендгенска дифракција на праху потврдила је формирање NiO и α-Fe2O3 кристалних фаза велике чистоће. Просечне димензије кристалита α-Fe2O3 су биле око пет пута веће у односу на кристалите NiO. ИЦ спектри синтетисаних материјала показују карактеристичне траке за наноструктуре NiO и α-Fe2O3. За визуелизацију морфологије и одређивање хемијског састава финалних производа коришћене су скенирајућа електронска микроскопија и енергијски дисперзивна рендгенска спектроскопија. Термогравиметријска анализа је омогућила боље разумевање термичког понашања прекурсора. Ова брза и лако изводљива метода синтезе отвара широк спектар примене добијених материјала, нарочито због своје економске исплативости.

AB  - The reaction of (E)-N,N,N-trimethyl-2-oxo-2-(2-(1-(pyridin-2-yl)ethylidene)hydrazinyl)ethan-1-aminium-chloride (HLCl) with copper(II) perchlorate led to mononuclear [CuLCl]ClO4 complex (1). The same reaction with excess of sodium azide gives dinuclear azido double end-on bridged Cu(II) complex [Cu2L2(μ-1,1-N3)2](ClO4)2 (2). In both complexes hydrazone ligand is NNO coordinated in monodeprotonated formally neutral zwitter-ionic form. Complexes were characterized by elemental analysis, IR spectroscopy and single‐crystal X‐ray crystallography. Variable‐temperature magnetic susceptibility measurements for dinuclear Cu(II) complex showed intra-dimer ferromagnetic coupling between Cu(II) ions (J = 7.4 cm–1). DFT-BS calculations provided explanation for magnetic properties of dinuclear Cu(II) complex. Both complexes were shown to highly efficiently catalyze the N-arylation of imidazole and benzimidazole with electron-poor or electron-rich aryl iodides, under user-friendly and sustainable conditions.

AB  - Magnetic anisotropy in pentagonal bipyramidal complexes of Co(II) (1 and 2), Fe(III) (3 and 4), and Ni(II) (5) with a 2,2′-[2,6-pyridinediylbis(ethylidyne-1-hydrazinyl-2-ylidene)]bis[N,N,N-trimethyl-2-oxoethanaminium] equatorial ligand and isothiocyanato axial ligands has been investigated by magnetic susceptibility measurements, powder X-band electron paramagnetic resonance (EPR) spectroscopy, Mössbauer spectroscopy, ab initio, and ligand-field density functional theory (LFDFT) calculations. The studied complexes display three distinct types of magnetic anisotropy. Co(II) complexes (1 and 2) show an easy plane anisotropy with large and positive D values and negligible rhombicity. The Ni(II) complex (5) has uniaxial magnetic anisotropy with a negative D value. Fe(III) complexes (3 and 4) have small zero-field splitting (ZFS) parameters. Theoretical modeling is used to rationalize the magnetic anisotropy in these systems and to identify the most important excited states that are responsible for the zero-field splitting. These excitations are a consequence of the electronic structure of the central metal ion in ideal pentagonal bipyramidal coordination.

AB  - Magnetic anisotropy in pentagonal bipyramidal complexes of Co(II) (1 and 2), Fe(III) (3 and 4), and Ni(II) (5) with a 2,2′-[2,6-pyridinediylbis(ethylidyne-1-hydrazinyl-2-ylidene)]bis[N,N,N-trimethyl-2-oxoethanaminium] equatorial ligand and isothiocyanato axial ligands has been investigated by magnetic susceptibility measurements, powder X-band electron paramagnetic resonance (EPR) spectroscopy, Mössbauer spectroscopy, ab initio, and ligand-field density functional theory (LFDFT) calculations. The studied complexes display three distinct types of magnetic anisotropy. Co(II) complexes (1 and 2) show an easy plane anisotropy with large and positive D values and negligible rhombicity. The Ni(II) complex (5) has uniaxial magnetic anisotropy with a negative D value. Fe(III) complexes (3 and 4) have small zero-field splitting (ZFS) parameters. Theoretical modeling is used to rationalize the magnetic anisotropy in these systems and to identify the most important excited states that are responsible for the zero-field splitting. These excitations are a consequence of the electronic structure of the central metal ion in ideal pentagonal bipyramidal coordination.

AB  - Cobalt-ferrite (CoFe2O4) and starch-coated CoFe2O4 nanoparticles were prepared by themechanochemical method and carefully chosen as adsorbents for Cr(VI) removal fromwastewater. The kinetic study, adsorption isotherms and influence of pH, contact time andinterfering ions were investigated to have deeper insight into adsorbent quality. UV/Visspectroscopy confirmed that the dominant adsorption mechanism is the electrostaticattraction at lower pH values. The study showed there was no significant change inadsorption efficiency for starch-coated nanoparticles. However, starch as a natural andbiocompatible compound can enhance nanoparticles water dispersibility. The advantage ofsuch materials is that saturation time does not exceed 20 minutes. Therefore, the as-preparedand starch-coated CoFe2O4 presents very efficient material for application in the field ofwater remediation.

AB  - The isothiocyanato Zn(II) complex (1) and mixed isothiocyanato/thiocyanato Cd(II) complex (2) with the condensation product of 2-acetylpyridine and trimethylammoniumacetohydrazide chloride (Girard's T reagent) (HLCl) were investigated both experimentally and theoretically. The crystal structures of both complexes showed tridentate N2O coordination of hydrazine ligand. In complex 1 square-pyramidal coordination surrounding of Zn(II) consists of deprotonated hydrazone ligand and two isothiocyanato ligands, while in octahedral Cd(II) complex ligand is coordinated without deprotonation as a positively charged species and coordination geometry is completed with two N-coordinated and one S-coordinated NCS- anions. NMR spectroscopy and molar conductivity results for Cd(II) and Zn(II) complexes indicated their instability in solution. DFT calculations were performed to explain coordination preference and stability of complexes 1 and 2 in solid state and in solution. The obtained Cd(II) complex is the first reported mononuclear pseudohalide/halide Cd(II) complex with quinoline-/pyridine-based hydrazone ligands possessing octahedral geometry in solid state. In this complex, H-bonding has significant impact on coordination number and supramolecular assembly in solid state.

AB  - The mixed chloride-azide [ZnL(N-3)(1.65)Cl-0.35] (1) and chloride-isocyanate [CdL(NCO)(1.64)Cl-0.36] (2) complexes with the condensation product of 2-quinolinecarboxaldehyde and trimethylammonium aceto-hydrazide chloride (Girard's T reagent) (HLCl) have been prepared and characterized by X-ray crystallography. In complexes 1 and 2, Znl and Cd1 ions, respectively, are five-coordinated in a distorted square based pyramidal geometry with NNO set of donor atoms of deprotonated hydrazone ligand and two monodentate ligands N-3(-) and/or N-3(-) and Cl- in the case of I and OCN- and/or OCN- and Cl- in the case of 2. The structural parameters of 1 and 2 have been discussed in relation to those of previously reported M(II) complexes with the same hydrazone ligand. Density functional theory calculations have been employed to study the interaction between the Zn2+ and Cd2+ ions and ligands. High affinity of ligands towards the Zn2+ and Cd2+ ions are predicted for both complexes.

AB  - Octahedral Co(III) complexes with heteroaromatic hydrazones ((E)-N,N,N-trimethyl-2-oxo-2-(2-(1-(pyridin-2-yl)ethylidene)hydrazinyl)ethan-1-aminium chloride and (E)-2-(1-(thiazol-2-yl)ethylidene)hydrazine-1-carbothioamide) and tetraisothiocyanato Co(II) complex anions have been synthesized, characterized by elemental analysis, IR and NMR spectroscopy, single-crystal X-ray diffraction and magnetic measurements. NMR spectroscopy showed that octahedral Co(III) complex cations of both compounds are stable in DMSO solution. Measured effective magnetic moments, which completely originates from complex anion [Co(NCS)(4)](2-) are practically constant and very close to the expected value for Co2+ ion with spin S = 3/2 and completely quenched orbital angular momentum. Co(III) ions in octahedral complex cations are in a low spin magnetic state with S = 0 and do not contribute to the magnetic signal.

The octahedral geometry of the Fe(III) complex consists of the deprotonated form of the hydrazone ligand coordinated through the pyridine nitrogen, azomethine nitrogen and carbonyl oxygen atoms with three isothiocyanato ligands in the remaining coordination places. The measured effective magnetic moment for Fe(III) complex corresponds to high spin Fe(III) ion. The hydrazone ligand and its Fe(III) complex showed lower activity against the tested microbial strains than standard antimicrobial drugs.

In complexes 1 and 2, Znl and Cd1 ions, respectively, are five-coordinated in a distorted square based pyramidal geometry with NNO set of donor atoms of deprotonated hydrazone ligand and two monodentate ligands N-3(-) and/or N-3(-) and Cl- in the case of I and OCN- and/or OCN- and Cl- in the case of 2. The structural parameters of 1 and 2 have been discussed in relation to those of previously reported M(II) complexes with the same hydrazone ligand. Density functional theory calculations have been employed to study the interaction between the Zn2+ and Cd2+ ions and ligands. High affinity of ligands towards the Zn2+ and Cd2+ ions are predicted for both complexes.

AB  - Pentagonal-bipyramidal complexes of 2,6-diacetylpyridine bis(acylhydrazone) ligands
are attractive field of research not only in structural inorganic chemistry and magnetochemistry, but also in bioinorganic chemistry since they exhibit cytotoxic, antimicrobial, SOD mimetic, DNA/RNA binding and nuclease activity. In this work we investigated antitumor and antimicrobial activity of pentagonal-bipyramidal isothiocyanato complexes of Mn(II) ([Mn(H2L)(NCS)2](SCN)2·CH3OH) (1), Ni(II)([Ni(H2L)(NCS)2](SCN)2·2H2O) (2), Co(II) ([Co(H2L)(NCS)2](SCN)2·2H2O (3) and
[Co(H2L)(NCS)2][Co(NCS)4]·2H2O) (4), Zn(II) ([Zn(H2L)(NCS)2][Zn(NCS)4]·2H2O) (5), Cd(II) ([Cd(H2L)(NCS)2][Cd(NCS)4]·2H2O) (6) and Fe(III) ([Fe(L)(NCS)2](SCN)·2H2O (7) and [Fe(L)(NCS)2][Fe(NCS)5(H2O)]·4H2O) (8), with the condensation product of 2,6-diacetylpyridine and Girard’s T reagent (H2LCl2). The complexes showed moderate to low cytotoxic activities towards five tested human cancer cell lines (HeLa, MDA-MB-453, K562, LS174 and A549), while the ligand was inactive. The best activity was observed in the case of complexes 8, 4 and 6. The potential of the most active complexes to induce HeLa and K562 cell cycle perturbations was also studied. Cd(II) complex (6) caused significant increase of apoptotic subG1 cells in both cell lines. Fe(III) complex (8) induced significant changes in cell cycle phase distribution only in HeLa cells. Morphological changes in HeLa cells treated with complexes 8, 4 and 6 were also indicative of apoptosis, with complex 6 having again the most pronounced effect. Complexes 8, 4 and 6 bind to
DNA, most probably by electrostatic interactions, and perturb DNA structure. Complexes 4 and 8 cause cleavage of plasmid DNA in vitro. Iron (III) complexes showed better antimicrobial activity than complexes of other metals with this ligand, but lower than activity of standard antimicrobial drugs.

In this work we investigated antitumor and antimicrobial activity of pentagonal-bipyramidal isothiocyanato complexes of Mn(II) ([Mn(H2L)(NCS)2](SCN)2·CH3OH) (1), Ni(II)([Ni(H2L)(NCS)2](SCN)2·2H2O) (2), Co(II) ([Co(H2L)(NCS)2](SCN)2·2H2O (3) and
[Co(H2L)(NCS)2][Co(NCS)4]·2H2O) (4), Zn(II) ([Zn(H2L)(NCS)2][Zn(NCS)4]·2H2O) (5), Cd(II) ([Cd(H2L)(NCS)2][Cd(NCS)4]·2H2O) (6) and Fe(III) ([Fe(L)(NCS)2](SCN)·2H2O (7) and [Fe(L)(NCS)2][Fe(NCS)5(H2O)]·4H2O) (8), with the condensation product of 2,6-diacetylpyridine and Girard’s T reagent (H2LCl2). The complexes showed moderate to low cytotoxic activities towards five tested human cancer cell lines (HeLa, MDA-MB-453, K562, LS174 and A549), while the ligand was inactive. The best activity was observed in the case of complexes 8, 4 and 6. The potential of the most active complexes to induce HeLa and K562 cell cycle perturbations was also studied. Cd(II) complex (6) caused significant increase of apoptotic subG1 cells in both cell lines. Fe(III) complex (8) induced significant changes in cell cycle phase distribution only in HeLa cells. Morphological changes in HeLa cells treated with complexes 8, 4 and 6 were also indicative of apoptosis, with complex 6 having again the most pronounced effect. Complexes 8, 4 and 6 bind to
DNA, most probably by electrostatic interactions, and perturb DNA structure. Complexes 4 and 8 cause cleavage of plasmid DNA in vitro. Iron (III) complexes showed better antimicrobial activity than complexes of other metals with this ligand, but lower than activity of standard antimicrobial drugs.",

AB  - Octahedral Co(III) complexes with heteroaromatic hydrazones ((E)-N,N,N-trimethyl-2-oxo-2-(2-(1-(pyridin-2-yl)ethylidene)hydrazinyl)ethan-1-aminium chloride and (E)-2-(1-(thiazol-2-yl)ethylidene)hydrazine-1-carbothioamide) and tetraisothiocyanato Co(II) complex anions have been synthesized, characterized by elemental analysis, IR and NMR spectroscopy, single-crystal X-ray diffraction and magnetic measurements. NMR spectroscopy showed that octahedral Co(III) complex cations of both compounds are stable in DMSO solution. Measured effective magnetic moments, which completely originates from complex anion [Co(NCS)(4)](2-) are practically constant and very close to the expected value for Co2+ ion with spin S = 3/2 and completely quenched orbital angular momentum. Co(III) ions in octahedral complex cations are in a low spin magnetic state with S = 0 and do not contribute to the magnetic signal.
