Abstract

Co (II), Cu (II), Mn (II), Ni (II) and Zn (II) complexes of a novel bisazo dye 2, 21 [benzene-1, 3-diyl di (E) diazene 2, 1-diyl] dianiline were synthesized. Characterization of the ligand and metal complexes has been done on the basis of elemental analysis, mass, FT-IR, 1H NMR, magnetic data and thermal analysis (TGA). From the analytical and thermal data, the stoichiometric ratio of the complexes has been found to be 1:1(metal-ligand). On the basis of physic-chemical data octahedral and square planar geometries were assigned for the azo complexes
