Schiff base complexes of transition metals are of particular interest to inorganic chemists because of their structural, spectral and chemical properties, which are often strongly dependant on the nature of the ligand structure. Large number of metal (II) complexes with Schiff-base ligands has been extensively studied for their interesting structural specialties, applications and properties. The coordination complexes of [Co(C15H15N2O2)2(H2O)2]. Cl2.2H2O and [Cu(C15H15N2O2)2(H2O)2].Cl2 with the Schiff base N-(4-Acetyl-phenyl)-acetimidic acid pyridine-3-yl ester derived from 4-aminoacetophenone with 3-acetoxypyridine have been synthesized and characterized by micro analytical data; FT-ir, UV-vis, FAB- mass and thermal analysis studies. Thermal data show degradation of complexes. We carried out thermal analysis at 10 . The activation thermodynamic parameters, such as activation energy (E*), entropy of activation (DS*), enthalpy of activation (DH*) and Gibbs free energy (DG*) have been calculated with the help of TG, DTA and DTG curves using Coats–Redfern (C-R) method. The stoichiometry of the complexes are in 1:2 (M:L) molar ratio. Synthesized complex has been tested for their reactivity and substitution behavior.
