Spectroscopic and Conductometric Studies of Hexamethylenediamine Schiff Base Cu (II) Complexes

Abstract

 
NEW Schiff base, o-HOC6H4CH:N(CH2)6N:CHC6H4OH-o, and its copper complexes have been characterized by using elemental analysis, UV-VIS, IR, 1H NMR, mass spectra, TGA, magnetic measurements and A.C electric conductivity. The formula of complexes were found (ML.nH2O.X) for 1:1 M:L where X=Cl-, Br-, NO3-, Ac-, L = Ligand. The ligand and its complexes have been characterized by IR ,UV-VIS, 1H NMR spectra and mass spectra which indicate that methine group and hydroxylic group in ortho position are involved in chelates besides to anions Cl-, Br-, NO3- and Ac-. Tetrahedral, octahedral and square planar geometries are proposed for the chelates based on their electronic spectra and magnetic moments. The investigated compounds behaved as semi- conducting materials.
