- 中文摘要: Reactions of H/sub 2/Os/sub 3/(CO)/sub 10/, 3, with the monophosphite-substituted and non-substituted tungsten propargyl and allenyl carbonyl complexes Cp(CO)/sub 2/LWCH/sub 2/C.ident.CH (1a, L=CO; 1b, L=P(OMe)/sub 3/) and Cp(CO)/sub 2/LWCH=C=CH/sub 2/ 2a, L=CO; 2b, L=P(OMe)/sub 3/) were investigated. In the reaction of lb with 3, a tetranuclear complex 4b is obtained. The molecules of 4b crystallize as Cp(CO)/sub 2/.lbrak.P(OMe)/sub 3/.rbrak.W(.mu.,.eta./sup 1/,.eta./sup 2/-CH/sub 2/CH=CH)(.mu. -H)Os/sub 3/(CO)/sub 10/ in space group P.1bar. with a=9.490(4), b=13.072(7), c=13.770(9).ANG., .alpha.=91.89(5),.beta.=106.71(5), .gamma.=104.07(4).degree., V=1577(2).ANG./sup 3/, Z=2. In the reaction of 2a with 3, from the reaction mixture exposed to air followed by workup using silica-gel packed column chromatography, a complex consisting of two triosmium clusters bridged by a hexadiene ligand from the coupling of allenyl ligand was obtained. The molecules of the hexanuclear complex crystallize as(CH/sub 2/CH=CH)/sub 2/(.mu.-H)/sub 2/Os/sub 6/(CO)/sub 20/ in space group P2/sub 1//c with a=14.448(7), b=13.689(4), c=19.224(4).ANG., .beta.=107.14(3).degree., V=3633(2).ANG./sup 3/, Z=4.
