Redox Chemistry of Dinuclear Molybdenum Dithiolene Complexes. Interconversion of the Bridging Disulfide and Sulfides
The redox properties of a photochromic dinuclear molybdenum complex, [Mo2(μ-S2)(μ-S2C2Ph2)2(S2C2Ph2)2] (1), were examined. Conventional and thin-layer cyclic voltammetric measurements showed that 1 undergoes two-electron reduction followed by chemical reactions to give [Mo2(μ-S)2(S2C2Ph2)4]2- (2), which was structurally characterized by X-ray crystallography. The overall two-electron oxidation product of 2 was converted to 1 via formation of four bonds.
