Metal complexes of Poly (vinyl alcohol) (PVA-oxi) with the formula [M (PVA- oxi)2 (Cl2)2] [M = Cu and Cd] were prepared using solution cast method. The atomic absorption; IR, UV-Vs spectroscopic techniques, molar ratio and molar conductance as well as the reduced viscosity of them were characterized. It was found that the prepared complexes were obtained from the ligand reaction with metal ions in a DMF solvent were ratio of metal: ligand (1:2) for complex Cu (II) ion and (1:1) for complexes Cd (II) ion. The results proved that the ligand (PVA-oxi) was bidentate ligand coordinated with metal ion through the oxygen atoms of carbonyl and hydroxylic groups of its chain, with an octahedral geometry around the metal ion Cu (II) complex and tetrahedron geometry for Cd (II) complex. The optical properties were examined using UV–Vis spectroscopy. The researchers studied the properties of the absorbance spectra, direct and indirect optical band gap energies of (PVA-oxi) and [M (PVA- oxi) 2 (Cl2)2] [M = Cu and Cd].Absorbance spectra, direct and indirect optical band gap energies were studied electrolyte for ligand and the prepared complexes. These band gap energies showed that the connection of the complexes is lower than of the ligand. The electrical conductivity of ligand and the prepared complexes electrolyte samples has been estimated by DC conductivity, which showed that the connection of the complexes was higher than the ligand.
