A New Dinuclear Molybdenum Compound, (Bu₄ N)[Mo₂(CO)₆(SPh)₂(CH₂CCH₃COO)]

The crystal structure of the title compound, tetrabutylammonium bis(μ-benzenethiolato-S:S)-μ-methacrylato-O:O′-bis(tricarbonylmolybdenum)(Mo—Mo), (C₁₆H₃₆N)[Mo₂(C₄H₅O₂)(C₆H₅S)₂(CO)₆], shows that it contains a Bu₄N⁺ cation and a dinuclear anion with three bridging ligands, i.e. [Mo₂(CO)₆(SPh)₂(CH₂CCH₃COO)]⁻; the α-methacrylate group acts as a bidentate bridging ligand and coordinates two Mo atoms to form a five-membered ring. The Mo—Mo bond distance is 2.9115 (5) Å and the O—C—O angle is 125.8 (4)°.
