PHYSICO-CHEMICAL INVESTIGATION ON SOME CARBODITHIOATE COMPLEXES OF OXOVANADIUM (IV)

Author(s): Rojila Puri

Some carbodithioate complexes of oxovanadium(IV) with general formulae: [VO(4-RPipzcdtH)2B]SO4 and [VO(4-EtPipzcdt)2B] (B = nil or Py, (R = M, Et and Pipzcdt= piperazine carbodithioate) have been prepared and characterized by elemental analysis, molar conductance, infrared, solution electronic absorption and proton NMR spectral, and room temperature magnetic susceptibilitymeasurements. The oxovanadium (IV) complexes exhibit 1:1 electrolytic nature except [VO(4-EtPipzcdt)2B] (B = Nil or Py) which exhibit non electrolytic nature. A square pyramidal geometry and presence of antiferromagnetic interactions for Zwitterionic and normal carbodithioate complexes of oxovanadium(IV), viz. [VO(4-RPipzcdtH)2]SO4, [VO(4-EtPipzcdt)2]; and octahedral geometry for their pyridine adducts have been proposed.
