Silylalkyne- and Silylvinylidene-Bridged Mixed Metal ClustersAttempts to incorporate silylalkynes into FeCo2 or RuCo2 clusters by means of cluster buildup or capping reactions are reported. From RuCo2(CO)11 and Me3SiC≡CMe were obtained RuCo2(CO)9(μ3-Me3SiC≡CMe) (5) and its more stable isomer RuCo2(CO)9(μ3-C=C(Me)SiMe3) (6). Of the latter the isonitrile derivative 8 was characterized by structure determination. The silylalkyne-bridged cluster 5 is very prone to desilylation forming RuCo2(CO)9(μ3-HC≡CMe) (11). The silylvinylidenebridged cluster 6 undergoes cluster expansion with CpRh(CO)2 to form RuCo2RhCp(CO)8(μ4-Me3siC≡CMe) (12), which again bears the silylalkyne ligand.
