Abstract
Cobalt (Π), Nickel (Π) and Copper (Π) complexes, with Schiff base ligand derived from 1, 6- diaminohexane and salicyladehyde (salhex) have been synthesized and characterized by elemental analysis, conductance measurements, magnetic susceptibility measurements, IR, electronic spectra, ESR spectral studies and thermal analysis. IR spectra suggested that salhex acts as tetra dentate dibasic ligand. The possible geometries of the complexes are assigned on the basis of ESR, electronic spectra as well as the magnetic moment values. The thermal behaviour of Cu (Π) complexes is studied using thermogravimetric analysis (TGA) technique. The different thermodynamic and kinetic parameters are calculated using Coats-Redfern method.
