Generation of Oxo-Carbide Clusters from Direct Scission of a Coordinated Carbonyl Ligand: Molecular Structures of Cp₂W₂Ru₃(CO)₁₃ and Cp*W(O)Cp*WRu₃(μ₅-C)(CO)₁₁

In this paper, we report the synthesis and characterization of heterometallic carbonyl clusters Cp₂W₂Ru₃(CO)₁₃ and LW(O)L'WRu₃(μ₅-C)(CO)₁₁, L, L' = Cp, Cp^*. Formation of the latter oxo-carbido clusters represents a unique example of direct scission of the C-O bond. The initial spectroscopic analysis confirms that the complex is identical to the partially characterized cluster complex synthesized from the photochemical reaction of [CpW(CO)₃]₂ with Ru₃(CO)₉BH₅.
