The complexes [Mo2(μ-η2-Me3SiC 2C≡CSiMe3)(CO)4(cp)2], [Pt(η2-Me3SiC2C≡CSiMe 3)(PPh3)2] and Ru3(μ3-η2-Me3SiC 2C≡CSiMe3)(μ-CO)(CO)9] have been prepared. Further reaction of the first with [Co2(CO)8] gives [{Mo2(CO)4(cp)2}{Co2(CO) 6}(μ-η2:μ-η2-Me 3SiC2C2SiMe3)]. Desilylation of [Co2(μ-η2-Me3SiC 2C≡CSiMe3)-(μ-dppm)n(CO) 6-2n](n = 0 or 1, dppm = Ph2PCH2PPh2) gave [Co2(μ-η2-RC2C≡CH)(μ-dppm) n(CO)6-2n] (n = 0, R = H; n = 1, R = SiMe3 or H). The first dppm complex adds across the M-M bonds in [Re2(CO)8-(NCMe)2] and [Ru3(CO)12] to give [Re2(μ-H){μ-η1:η2;μ-η 2-C2C2SiMe3[Co 2(μ-dppm)(CO)4]}(CO)8] and [Ru3(μ-H){μ3-eta;1:η 2;μ-η2-C2C2SiMe 3[Co2(μ-dppm)(CO)4]}(CO)9], respectively, while both dppm complexes react with [WCl(CO)3(cp)] to give [Co2{μ-η2-RC2C≡C[W(CO) 3(cp)]}(μ-dppm)(CO)4] (R = H or SiMe3). Auration of the HC2C2SiMe3 complex with [AuCl(PPh3)]-1,8-diazabicyclo[5.4.0]undec-7-ene gave [Co2{μ-η2-Me3SiC 2C≡C[Au(PPh3)]}(μ-dppm)(CO)4]. Addition of HC≡CC≡CSiMe3 to [Ru3(μ-dppm)2(CO)8] gave [Ru3(μ-H)(μ3-η1:η 2-C2C≡CSiMe3)(μ-dppm) 2(CO)5]. The complex [Os3(CO10(NCMe)2] reacts with HC≡CC≡CSiMe3 to give isomers of [Os3(μ3-η2-HC2C 2SiMe3)(μ-CO)(CO)9]; the mixture reacts with [Co2(CO)8] to give one isomer of [Os3{μ3-η2;μ-η 2-HC2C2SiMe3[Co2(CO) 6]}(μ-CO)(CO)9] in which the Co2 moiety bridges the C≡CSiMe3 portion of the diyne. The crystal structures of five of the complexes have been determined.
