COMPARATIVE STUDIES OF SOLVATOCHROMISM BEHAVIOUR OF COPPER(I1) AND NICKEL(I1) SCHIFF BASE COMPLEXES
A series of Schiff Bases of Ni(II) and Cu(II) using acetylacetone (acac), salicylaldehyde (sal), ethylenediamine (en), and o-phenylendiarnine (dabe) were prepared and characterized. The electronic spectra of some copper chelates in various organic solvents depend strongly on the solvent used and the d-d band of Cu(II) shifts to red with the increase of the Donor Number (DN) of solvent. The ...
متن کاملTEMPLATE SYNTHESIS, CHARACTERIZATION OF HIGHLY UNSYMMETRICAL TETRADENTATE SCHIFF BASE COMPLEXES OF NICKEL (II) AND COPPER (II)
Nickel (II) and copper (II) complexes of highly unsymmetrical tetradentate Schiff base have been synthesized by the template reaction of half-units N-(1-hydroxy-2-acetonaphtone)-1-amino-2-phenyleneimine (HL) and N-(2-hydroxyacetophenone)-1-amino-2-phenyleneimine (HL1) with the glyoxalphenylhydrazone. The complexes have been characterized by elemental analyses, conductance, IR, 1H NMR and UV spe...
متن کاملStudy the Interaction of Ni Complex of Tetradentate Schiff Base Ligand with HEN Egg White Lysozyme
AbstractInteraction of Ni complex(Salen= N, N´-ethylene bis(salicylideneimine)) with hen egg-white lysozyme (HEWL) was studied by absorption spectroscopy, competitive binding study and thermal denaturation study. The protein binding affinity of Ni complex was found to be (3.0×103M−1). The binding plot obtained from the absorption titration data gives a binding constant of 2.4 (± 0.3)×103 M...

متن کاملTemplate Synthesis, Structural Characterization and Antibacterial Activity of an Unsymmetrical Tridentate Schiff Base Nickel(II) Complex
Nickel(II) complex of [NiL2](ClO4)2, where L is an unsymmetrical tridentate ligand of 2-(2-aminoethyl)imino-3-butanone oximehas been synthesized by a template condensation reaction. The complex was characterized on the basis of microanalytical, spectroscopic, and other physicochemical properties. X-ray diffraction study of the complex revea...
