The metal isotope technique is applied to the investigation of the metal-ligand bands in the i.r. spectra of complexes of type: Cu(PAN)X and Cu(PAN)2 where X = Cl, Br and PAN symbolizes 1-(2-pyridylazo)-2-naphtol.For the Cu(PAN)Cl complex, bands 337, 274 and 196 cm-1 were assigned to the Cu-O, Cu-N-py and Cu-N-azo stretching vibrations, respectively.Two Cu-Cl stretching vibrations have been found at 298 and 236 cm-1.The spectrum indicates that in the Cu(PAN)2 complex.PAN acts as a bidentate ligand as only Cu-O and Cu-N-azo bonds are formed.
