- 中文摘要: Decarbonylation of triosmium methylthiolato cluster Os/sub 3/(CO)/sub 10/(.mu.-H)(.mu.-SMe) with Me/sub 3/NO in acetonitrile solution gave cluster Os/sub 3/(CO)/sub 9/(NCMe)(.mu.-H)(.mu.-SMe) (1), in which one axial CO on the non-bridged Os atom is replaced by an acetonitrile ligand. Crystal data for C/sub 17/H/sub 10/O/sub 11/SWOs/sub 3/: space group P bca, a=14.491(1), b=16.107(5), c=16.639(5).ANG., Z=8; R/sub F/=0.037, R/sub w/=0.033. Treatment of C/sub 17/H/sub 10/O/sub 11/SWOs/sub 3/ with CpW(CO)/sub 3/H in refluxing THF solution yielded two cluster compounds with formula CpWOs/sub 3/(CO)/sub 11/(.mu.-H)/sub 2/(.mu./sub 3/-SMe) (2) and CpWOs/sub 3/(CO)/sub 11/(.mu.-H)/sub 2/(.mu.-SMe) (3) as the principle products. The first possesses a spiked-triangular geometry with a triply bridging thiolato ligand and the second adopts a butterfly metal core arrangement with an edge-bridging thiolato grouping. The structure of (2) was characterized by single- crystal X-ray diffraction. Crystal data: space group P.1bar., a=8.865(5), b=8.959(3), c=16.688(4).ANG.,.alpha.=103.49(2), .beta.=93.58(3), .gamma.=113.03(4).degree., Z=2, R/sub F/=0.034, R/sub w/=0.035.
