The reaction of a dilute solution of [CpMo(μ-S)(μ-SH)]2 (Cp = C5H5) with 1 equiv of phenylacetylene under air leads to the formation of anti-CpMo(O)(μ-S)2Mo(SCH=C(Ph)S)Cp (1) in 20% yield. Both syn and anti isomers of 1 can be synthesized by the reaction of [CpMo(SCH=C(Ph)S)]2 with trifluoroacetic acid under air. The anti isomer has been characterized by an X-ray diffraction study. The complex crystallizes in space group Pna21, with a = 10.284 (6) A?, b = 15.175 (8) A?, c = 12.018 (7) A?, and V = 1875 (2) A?3. The dinuclear complex contains two μ-sulfido ligands in a nonplanar Mo2S2 core, a terminal oxo ligand on one CpMo site, and a bidentate styrenedithiolate ligand coordinated to the second CpMo site. The cyclopentadienyl ligands are anti with respect to the metal-metal vector. The terminal oxo ligand in 1 is displaced by sulfide in the reaction with hexamethyldisilthiane. Complex 1 reacts with hydrogen to form water, (CpMo)2S4 derivatives, and organic products that result from hydrogenation and hydrolysis of the styrenedithiolate ligand.
