Abstract

We report the first examples of the carbide ligand in (Cy ₃ P) ₂ Cl ₂ Ru≡C (RuC) developing into a μ ₃ ligand toward metal centers. Conventionally, sterics exclude this coordination mode, but Fe ₂ (CO) ₉ and Co ₂ (CO) ₈ expel bridging CO ligands upon reaction with RuC to form trimetallic (Cy ₃ P) ₂ Cl ₂ Ru=CFe ₂ (CO) ₈ (RuCFe ₂ ) and (Cy ₃ P) ₂ Cl ₂ Ru=CCo ₂ (CO) ₇ (RuCCo ₂ ) complexes. Thus, the proximity offered by metal-metal associations in bimetallic carbonyl complexes allows the formation of trinuclear carbide complexes as verified by NMR, Mössbauer, and X-ray spectroscopic techniques.
