Sulfur K-edge X-ray absorption spectroscopy (XAS) and density functional theory (DFT) calculations have been used to determine the electronic structures of two Mo bis-dithiolene complexes, [Mo(OSi)(bdt)(2)](1-) and [MoO(OSi)(bdt)(2)](1-), where OSi = [OSiPh(2)(t)Bu](1-) and bdt = benzene-1,2-dithiolate(2-), that model the Mo(IV) and Mo(VI)=O states of the DMSO reductase family of molybdenum enzymes. These results show that the Mo(IV) complex undergoes metal-based oxidation unlike Mo tris-dithiol ...[more]
