the Schiff base 2,6-C5H3N(CCH3=NC6H5)2 derived from 2,6-diacetylpyridine and anline has been prepared. Complexes of the type M[C5H3N(CCH3=NC6H5)2]2(PF6)2(M=Cu2+,Co2+,Zn2+) have been isolated. The Schiff base and complexes were characterized by element analysis, IR spectra, conductivity, magnetic susceptibility and TG. The thermal stability and non-isothermal kinetics of thermal decomposition reaction were also investigated by TG-DTG technique. The possible thermode composition were deduced by means of integral and differntial equations. Saturated oxygenuptake of Co(Ⅱ) complex in N,N`-dimethyl formanide solvent at different temperatures was obtained by manometric oxygenuptake measurements. Oxygenation equibrium comstants and its thermo dynamic parameters△H°、△S° were calculated from the above measurements. The electro chemiacal Characterization of the ligand and Co(Ⅱ) complex were studied in methyl-cyanide solvent.
