Reduction of [Cp*2Mo2O5] by thioglycolic acid in an aqueous medium: Synthesis and structure of [{Cp*Mo(μ-SCH2COO)}2(μ-S)]

Résumé

Compound [Cp*2Mo2O5] reacts with thioglycolic acid, HSCH2COOH, in an acidic (CF3COOH) mixed water-methanol solvent, to yield compound [{Cp*Mo(μ-SCH2CO2)}2(μ-S)]. During this reaction, the thioglycolic acid acts as a reducing agent, as a ligand, and provides a sulfide ion for the Mo-S-Mo bridge. The molecular structure of the product can be described as containing two four-legged piano stools that share three legs. The Mo-Mo distance of 2.792(7) Å indicates metal-metal bonding, in agreement with the compound diamagnetism.
