Synthesis, chemical, and electrochemical studies of oxomolybdenum(IV) complexes with two tridentate ONS donor ligands

Abstract

This manuscript reports the synthesis, characterization, chemical, and electrochemical studies of several oxomolybdenum (IV) complexes of tridentate ONS donor ligands obtained by the condensation of 2-hydroxyacetophenone with S-benzyl and S-methyl dithiocarbazates. The complexes are of the forms [Mo^IVOL] and [Mo^IVOL(N–N)], where N–N = 2,2′-bipyridine and 1,10-phenanthroline, derived from the corresponding [MoO₂L] complexes through oxo abstraction by triphenylphosphine in the absence/presence of N–N bidentate donors. Electrochemical behavior of these complexes have been investigated for insight into the redox behavior of the Mo(IV) centers of these complexes.
