Low molecular weight, low symmetric complexes simulating blue copper protein have been prepared by a reaction between salicylidene-4-aminoantipyrinyl-2-imino pyridine and metal salts. The complexes were characterized by elemental analysis, molar conductivity, magnetic susceptibility data, IR, 1 H NMR, UV-Vis, FAB-Mass and EPR spectral studies. The physicochemical studies and spectral data indicate that the ligand acts as a monovalent tridentate chelating agent. All the complexes have the general composition MLX (M= Cu(II), Ni(II), Co(II) and Zn(II); L = Schiff base and X = Cl/Br/OAc). The UV-Vis., cyclic voltammetry and EPR spectral data of the complexes suggested that [CuLCl] complex is mimic the blue copper model type 1 proteins. But other two copper complexes are square planar geometry around the central metal ion and they were non-model complexes.
