Abstract	We report the synthesis of some heterobimetallic carbonyl clusters of groups 8 and 9 derived from diethynylsilane and diethynyldisilane ligands. The triosmium carbonyl clusters containing a pendant acetylene unit [(μ-CO)Os$_{3}$(CO)$_{9}$(μ$_{3}$-η$^{2}$-HC≡C-E-C≡CH)] [E = Si(CH$_{3}$)$_{2}$, Si(CH$_{3}$)$_{2}$–Si(CH$_{3}$)$_{2}$ and SiPh$_{2}$] were prepared and subsequently used for mixed-metal cluster formation. New diyne complexes of the type [{(μ-CO)Os$_{3}$(CO)$_{9}$}{Co$_{2}$(CO)$_{6}$}(μ$_{3}$-η$^{2}$:η$^{2}$-diyne)] and [{(μ-CO)Os$_{3}$(CO)$_{9}$}{(μ-H)Ru$_{3}$(CO)$_{9}$}(μ$_{3}$-η$^{2}$:μ$_{3}$-η$^{2}$, η$^{2}$-diyne)] [diyne = HC≡CSi(CH$_{3}$)$_{2}$C≡CH, HC≡CSi(CH$_{3}$)$_{2}$–Si(CH$_{3}$)$_{2}$C≡CH or HC≡CSi(Ph)$_{2}$C≡CH] have been prepared in good yields from the reaction of [(μ-CO)Os$_{3}$(CO)$_{9}$(μ$_{3}$-η$^{2}$-HC≡C-E-C≡CH)] with a molar equivalent of [Co$_{2}$(CO)$_{8}$] and [Ru$_{3}$(CO)$_{12}$], respectively. All the new heterobimetallic compounds have been characterized by IR and $^{1}$H NMR spectroscopy and mass spectrometry. The X-ray crystal structures and computational analyses based on density functional theory of these three molecules have been studied. Structurally, the dicobalt species adopts a pseudo-tetrahedral Co$_{2}$C$_{2}$ core with the alkyne bond which lies essentially perpendicular to the Co–Co vector. For the mixed osmium–ruthenium analogue, the hexanuclear carbonyl cluster consist of two trinuclear metal cores with the μ$_{3}$-(η$^{2}$-\|\|) bonding mode for the acetylene group in the former case and the μ$_{3}$-η$^{2}$, η$^{2}$ bonding mode in the latter one.
