- 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.
