摘要：

Copper(II), cobalt(II) and nickel(II) complexes of ligands such as N-(3-hydroxy salicylidene)-3, 5-di(tert-butyl)-4-hydroxyaniline (L 1H) and N-(3, 4-dihydroxysalicylidene)-3, 5-di(tert-butyl)-4-hydroxyaniline (L2H) have been prepared and characterized by elemental analyses, magnetic moment, infrared, electronic absorption spectral data and molar conductance. Thermal decomposition studies show that the copper, cobalt and nickel complexes decompose with the loss of hydrated water followed by loss of the organic ligand to give the metal oxides. The 1H and 13C NMR spectra of the Schiff base ligands have been recorded.
