摘要：

The equilibrium quotient of the adduct formation of [Co(Salen)PPh3]ClO4 center dot H2O and [Co(7,7'-dimethylSalen)PPh3]ClO4 center dot H2O, as acceptor with amines donors are studied by spectrophotometer. Thermodynamics of these pentacoordinate cobalt(III) Schiff-base complexes have been examined with n-butylamine, sec-butylamine, tert-butylamine, benzylamine and diethylamine in constant ionic strength of 0.1 M sodium perchlorate and acetonitrile solvent at room temperature. We aimed to investigate the effects of different electronic and steric situations of donor and acceptor by comparing their equilibrium quotient for any adduct.
