摘要：

Compound [CP*2Mo2O5] reacts with thioglycolic acid, HSCH2COOH, in an acidic (CF3COOH) mixed water-methanol solvent, to yield compound [{Cp*Mo(mu-SCH2CO2)}(2)(mu-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) angstrom indicates metal-metal bonding, in agreement with the compound diamagnetism. (c) 2005 Elsevier B.V. All rights reserved.
