Abstract: Copper(II) complexes of tetradentate Schiff bases N, N’–disalicylidene–1, 2–phenylenediamine(H2dsp), N, N’–disalicylidene–3, 4–diaminotoluene(H2dst), 4–nitro-N, N’–disalicylidene–1, 2–phenylenediamine(H2ndsp), N, N’–disalicylideneethylenediamine(H2salen) have been synthesized and characterized by elemental analysis, electronic spectra, IR spectra, magnetic susceptibility measurement, EPR, CV and thermal studies. TG studies show that Cu(dsp) and Cu(ndsp) complexes thermally degrade in two steps and Cu(dst) and Cu(salen) in one step. Kinetic and thermodynamic parameters have been computed from thermal decomposition data. The activation energies of both the thermal degradation step is found to lie in between 52–74 kJ mol−1.
