Abstract

Thermal decomposition of the known complex [Co(C₅Me₄Et) (C₂H₄)Me₂] gives the intermediate species 'Co(C₅Me₄Et)' which reacts with [OS₃(CO)₁₀H₂] to produce [Os₃Co(CO)₁₀(C₅Me₄Et)H₂]. This complex crystallises in the triclinic space group P1 with a = 9.072(4), b = 10.477(5), c = 13.921(7) Å, α = 95.80(3), β = 93.54(3), γ = 102.48(3)°, and Z = 2. The structure was solved by a combination of direct methods and Fourier-difference techniques and refined by blocked-cascade least squares to R = 0.039 for 3 084 diffractometer data. The Co(C₅Me₄Et) fragment caps the Os₃ triangle. Each Os atom is also co-ordinated to three terminal carbonyl groups while the tenth carbonyl bridges an Os-Co bond. The complex [Os₃Co(CO)₁₀(C₅Me₄Et)H₂] reacts with hydrogen to give [Os₃Co(CO)₉(C₅Me₄Et)H₄], and both clusters react with carbon monoxide under fairly mild conditions to yield [Os₃(CO)₁₂] and [Co(CO)₂(C₅Me₄Et)].
