description

Abstract The synthesis, characterization and spectroscopic properties of a group of Mo(VI) complexes having thiocarboxylate ligands of type [MoVIO2(O2CC(S)MePh-X)2]2 have been reported (X = H, p-Me, p-Cl). The peak potential for the Mo(VI) reduction increasing according to the electron-donor ability of X (Me > H > Cl). Reaction of these Mo(VI) complexes with their own free ligands has been studied by ESR and UV-Vis spectroscopy, yielding the monomeric [MoVO(O2CC(S)MePh-X)2]− as unique complex products. The kinetic study of this oxidation reaction has also been investigated.
