Binuclear Schiff base complexes derived from glycine (Gly) and 3-acetylpyridine (3-APy) in the presence of M(OAc)(2) [M = Co-II, Ni-II, Cu-II, Zn-II and Cd-II] have been synthesized. The role of pH in promoting the condensation of glycine and 3-acetylpyridine, as well as the substitution of acetates by hydroxide ion, has been discussed. Also, the reaction of glycine with 3-acetylpyridine in the presence of MCl2 [M = Co-II and Ni-II] and MCl3 [M = Fe-III and Cr-III] yields mono- and/or binuclear complexes containing both of glycine and 3-acetylpyridine without condensation. Both types of complex were isolated and characterized by chemical analysis, conductance, spectral (u.v.-vis., i.r., and H-1-n.m.r.), magnetic and thermal measurements.
