Abstract Coupling reaction of (3,5-Dichlorophenyldiazonium chloride) with 4,5-dipheny limidazole in alkaline alcoholic medium yielded a new azoligand 2-[(3,5-Dichloro phenyl)azo]- 4,5-diphenylimidazole (dcpai). The structure and nature of this organi ligand and its metal complexes with Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) wer established on the basis of available technique such as elemental analysis, mola conductance measurements, magnetic susceptibility, IR and electronic spectral data The spectral and analytical data revealed that this ligand coordinated through th nitrogen atom of azomethine group of heterocyclic imidazole ring and the othe nitrogen atom of azo group which is the farthest of imidazole molecule. The geometry of the prepared metal complexes are discussed based on analytical and spectral data.
