Abstract

The electrochemical behaviour of the new vanadium(IV) complex [VCl₃(SO₃Cpz₃)] (pz = pyrazolyl), obtained by reaction of VCl₃ with Li[SO₃Cpz₃], investigated by cyclic voltammetry and controlled potential electrolysis is reported and compared with those of hydrotris(pyrazolyl)borate vanadium(IV) complexes.

Keywords:Vanadium complexes, Tris(1-pyrazolyl)methanesulfonate; Tripodal ligands; Cyclic voltammetry.
