bis (Xylenedithiocarboxylate)oxovanadium(IV) and Adducts with Organic Bases

Abstract We report the synthesis and study of bis(xylene-dithiocarboxylate)oxovanadiuum(IV) and its adducts with cyclohexylaraine, piperidine, morpholine, piperazine and pyrrolidine. The compounds have been characterized by analytical, magnetochemical, IR and visible-UV spectral methods and analytical data, and are assigned respectively to the formula VO(C8H9CS2)2 and VO(C8H9CS2)2 B. The effect of adduct formation on the πv=o bond are discussed in terms of the IR (V=o, V-S and V-N stretching frequencies) and electronic spectra (d-d transitions).
