Abstract: The present paper describes the preparation and characterization of V-Cu complex in which sulfide anions and 4,4’-bipyridine act as ligands. As sulfide source, Na2S·9H2O has been used. The nature of the resulted compound depend strongly on the copper (II) to vanadium and metal to sulfide ratio as well as on the nature of the used ligand. The nature of the obtained compound with formula: [CuVOS2(4,4 ́-dpy)(OH)2·2H2O]n has been established on the basis of elemental analysis, spectral properties. The electronic spectrum shows the presence of VO (IV) species of C4νsymmetry and Cu (II) in octahedral surrounding. The IR spectrum proves the presence of the coordinated 4,4’-bipyridine and presence of the vanadyl ion.
