Abstract: Some new azo compounds were prepared by coupling the diazonium salts of amines and 2,7dihydroxynaphthalene and 1,6-dihydroxynaphthalene. The structure of azo compaunds were determined on the basis of elemental analyses, UV–vis, IR, 1 H-NMR spectra and also by aid of scannicing electron microscopy (SEM). Complexes of cobalt(II), nickel(II), copper(II) with a heterocyclic azo derivatives heve been synthesized and characterized. The composition of complexes have been established by analytical (elemental analysis and magnetic susceptibility measurements ) and spectral(UV–vis, IR) methods. Analytical data revealed that all the complexes exhibited 1:2 metal–ligand ratio. On the basis of magnetic susceptibility measurements, suitable geometry was proposed for each complex. IR spectra of complexes show that the ligands are coordinated to the metal ions in bidentate manner with ON donor sites of hydroxynaphthalene OH and azo N.
