Electrical conductance and solvation behaviour of [Ni(HL)(bipy)(H2O)](NO3)(ClO4)(H2O) and [Ni(HL)(dien)](ClO4)2(H2O), where HL = 2-[(1)-pyridin-2-ylmethylidene]benzohydrazide in various compositions (0-100 %) of H2O + DMSO in the temperature range 288.15 to 308.15 K have been studied by conductance measurement. The conductance data have been analyzed by Shedlovsky equation. The limiting molar conductance Λο has been decreased with the increase in the percentage of DMSO in the mixed solvent. This is due to increase in solvent-solvent interaction and increase in the dielectric constant. Owing to their high viscosity and molecular measurements of DMSO in water, lower specific conductance has been observed in H2O + DMSO. The KA values have been increased on increasing the temperature and increasing the percentage of DMSO in the mixed solvent presenting endothermic character of ionic association in this system. Activation energy of the rate process and related thermodynamic parameters have been evaluated and reported. Applying viscosity of the solvent/solvent mixture, Walden product Λoηo and effective radius r (Å) have been obtained and discussed. The results have been interpreted in terms of ion-solvent interactions and solvent-solvent interactions.

“…These enzymatic nickels are usually taking different electronic structures in different enzymatic states and/or different chemical environments [15]. Keeping the above facts in mind and in continuation of our school's research work on transition metal complexes [16][17][18] with Schiff bases, herein we report Synthesis, characterization, spectroscopic and redox properties of two new copper(II) and nickel(II) complexes are described. The structures of these complexes in the solid state have been determined by X-ray analysis.…”

“…Many potential hydrazone ligands have been synthesized using heteroaromatic carbonyl compounds in combination with different hydrazine derivatives [11][12][13]. Recently, hydrazones derived from 2-pyridine carboxaldehyde have been used to synthesize many biologically active metal complexes [14][15][16][17][18][19].…”

A new hydrazone, Z-ethyl 2-(pyridine-2yl-methylene) hydrazine carboxylate(C9H11N3O2; Hpyec) and its metal complexes bis(Z-ethyl 2-(pyridine-2yl-methylene) hydrazine carboxylate) nickel(II) monohydrate, [Ni(pyec)2]•H2O (1) and bis(acetato)(Z-ethyl 2-(pyridine-2yl-methylene) hydrazine carboxylate) cadmium (II), [Cd(Hpyec)(CH3COO)2](2), have been prepared by mechano-chemical syntheses and characterized by elemental analysis, UV-visible, IR and NMR spectroscopy, TG-DTA, and solid state emission techniques. The X-ray single crystal structures of both complexes were determined: in 1, the Ni 2+ ion is coordinated by two N, N, O-tridentate anionic ligands to generate a distorted cis-NiO2N4 octahedron. In 2, the cadmium atom is sevencoordinated by one neutral N,N.O-tridentate ligand and two chelating acetate ions to generate a very-distorted CdN2O5 pentagonal bipyramid with the Hpyec atoms occupying both axial and
