Peroxide oxygenation of μ-thiolate-μ-sulfide Mo(V) dimer complexes of the type [Mo2(NAr)2(S2P(OEt)2) 2(μO2CMe)(μ-SR)(μ-S)] yielded Mo2(μ-SO) and Mo2(μ-SO2) complexes, demonstrating the reactivity sequence μ-S > μ-SO ? μ-SR. Inversion isomers of the pyramidal sulfur site in the μ-SO bridge were observed, and the pyramidicity was confirmed crystallographically. Visible light photolysis of the Mo2(μ-SO2) complex liberated SO from the SO2 bridge and produced Mo2(μ-O) compounds. Crystallography of analogous Mo2(μ-S), Mo2(μ-SO), Mo2(μ-SO2), and Mo2(μ-O) complexes provided structural comparisons related to variations in the bridge functionality.
