摘要

A novel mixed-trribridged dimolybdenum(I) compound [Bu4N] [Mo2(μ-SPh)2(μ-Cl) (CO)6] (1) has been synthe sized from the reaction of Mo2 (CO)s (SPh)2 with Bu4NCl. Compound 1 was characterized by IR, UV-Vis and 1H, 13C, 95Mo NMR spectroscopic analyses. The electrochemical be havior was measured by cyclic voltammetry, indicating a quasi-reversible two-electron transfer in one step. The crystal structure determined by X-ray crystallography shows that 1 contains a [Mo2(μ-S)2(μ-Cl) ]- core with a planar Mo2S2 unit and a Cl bridge. The Mo－Mo distance is 0.28709(7) mn, and the Mo-Cl-Mo angle is 66.44(4)°. A newface-sharing bioctahedral structure is discussed.
