DIVALENT COBALT, COPPER AND ZINC-COMPLEXES OF N-SALICYLIDENEAMINO ACIDS

Complexes of Co-II, Cu-II and Zn-II with N-salicylidenamino acids have been prepared. Amino acids used were glycine, L-alanine and L-phenyla lanine. The Schiff bases function as terdentate with O, O and N donors from carboxylic, phenolic and imine groups respectively. An octahedra l geometry around Co-II and Zn-II and a square-planar geometry around Cu-II have been proposed.
