What Is the Nature of Interactions of BF4–, NO3–, and ClO4– to Cu(II) Complexes with Girard’s T Hydrazine? When Can Binuclear Complexes Be Formed?
(American Chemical Society (ACS), 2019)
In solid-state coordination chemistry, the coordination number of a metal center is not always unambiguously determined, as sometimes from the geometrical parameters it is not clear if ligands are directly bound to the ...
Spectroscopic and quantum chemical investigations of substituent effects on the azo-hydrazone tautomerism and acid-base properties of arylazo pyridone dyes
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
A series of 5-(4-substituted arylazo)-6-hydroxy-4-methyl-3-cyano-2-pyridone dyes was synthesized and the structure of the dyes was confirmed by UV-Vis, FT-IR, H-1 NMR and C-13 NMR spectroscopic techniques. The azo-hydrazone ...
A simulation of free radicals induced oxidation of dopamine in aqueous solution
(Elsevier, 2019)
Understanding the basic chemistry between highly reactive free radicals and dopamine is an important step in characterizing the antioxidative activity of catecholamine neurotransmitters. In this work, we simulated the ...

Structural aspects of 4-aminoquinolines as reversible inhibitors of human acetylcholinesterase and butyrylcholinesterase
(Elsevier Ireland Ltd, 2019)
Eight derivatives of 4-aminoquinolines differing in the substituents attached to the C(4)-amino group and C(7)were synthesised and tested as inhibitors of human acetylcholinesterase (AChE)and butyrylcholinesterase (BChE). ...
Theoretical study of substituent effects on structural properties of arylazo pyridone dyes
(Society of Physical Chemists of SerbiaDruštvo fizikohemičara Srbije, 2014)
Quantum chemical calculations performed by the density functional theory (DFT) were used to determine the structural parameters of arylazo pyridone dyes. The influence of electronic effects of substituent in diazo moiety ...
Synthesis, structures and electronic properties of Co(III) complexes with 2-quinolinecarboxaldehyde thio- and selenosemicarbazone: A combined experimental and theoretical study
(Serbian Chemical Soc, Belgrade, 2017)
Cobalt(III) complexes derived from thio-and selenosemicarbazone ligands have been studied to elucidate the nature and consequences of S to Se substitution on their possible biological activity. Solid state structures of ...
Absorption and fluorescence spectral properties of azo dyes based on 3-amido-6-hydroxy-4-methyl-2-pyridone: Solvent and substituent effects
(Elsevier, 2020)
A series of nine 5-(4-substituted phenylazo)-3-amido-6-hydroxy-4-methyl-2-pyridones were synthesized and characterized by FT–IR, 1H and 13C NMR, UV–Vis, and PL spectroscopy. Photophysical properties of the dyes were examined ...
Coordination preferences of Shiff base ligands with transition metals: DFT study
(Society of Biological Inorganic Chemistry, 2022)
To rationalize coordination preferences of the ligands to form mono- or binuclear complexes and coordinate differently, together with the electronic structure of transition metal ions, we performed Density Functional Theory ...
Modeling metal-ligand bonds – from ground to excited states
(Frankfurt, Germany : MBN Research Center gGmbH, 2022)
In this talk, our efforts in understanding and controlling metal-ligand bonding will be presented, mainly
based on the density functional calculations. The influence of the excited states on the electronic ground state ...
