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 ...
What is the nature of bonding in [Fe(CO)3(NO)]− and [Fe(CO)4]2−?
(Springer Nature, 2020)
To shed new light on the electronic structure of [Fe(CO)3(NO)]¯ complex ion, DFT-based analysis of the nature of chemical bonding has been performed. For this purpose, the extended transition state energy decomposition ...
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 ...
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 ...
Synthesis, crystal structure, magnetic properties and DFT study of dinuclear Ni(II) complex with the condensation product of 2-quinolinecarboxaldehyde and Girard's T reagent
(Oxford : Pergamon-Elsevier Science Ltd, 2017)
A dinuclear double end-on azido bridged KM complex [Ni2L2(mu-(1),(1)-N-3)(2)(N-3)(2)] (1) with the condensation product of 2-quinolinecarboxaldehyde and trimethylammonium acetohydrazide chloride (Girard's T reagent) (HLCl) ...
Crystal structures and DFT calculations of mixed chloride-azide zinc(II) and chloride-isocyanate cadmium(II) complexes with the condensation product of 2-quinolinecarboxaldehyde and Girard's T reagent
(Elsevier, 2018)
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 ...
Correlating Structure and KA2 Catalytic Activity of Zn(II) Hydrazone Complexes
(Wiley, 2023)
Two new Zn(II) complexes bearing tridentate hydrazone-based ligands with NNO or NNS donor atoms were synthesised and characterised by elemental analysis, infrared (IR) and nuclear magnetic resonance (NMR) spectroscopies, ...
Combined Experimental and Theoretical Investigation of the Origin of Magnetic Anisotropy in Pentagonal Bipyramidal Isothiocyanato Co(II), Ni(II), and Fe(III) Complexes with Quaternary-Ammonium-Functionalized 2,6-Diacetylpyridine Bisacylhydrazone
(American Chemical Society (ACS), 2019)
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] ...
Nickel(II) and nickel(III) Thiosemicarbazone and Hydrazone Complexes: An Unexpected Journey
(Elsevier, 2023)
In this paper, we report the synthesis, characterization, and X-ray structure analysis of one octahedral Ni(II) complex, [Ni(HL1 )2](BF4)2*H2O, formed by coordination of two ligands with NNS donor atom sets (HL1 ligand, ...
