Abstract

The reaction of the anion [Fe₄(CO)₁₃]^- with AuClPR₃ (R = Et, Ph) yields an anion which upon protonation gives the cluster Fe₄AuC(H)(CO)₁₂(PR₃). This complex is reversibly deprotonated in the presence of base and the resultant anion upon treatment with AuClPR₃ (R = Et, Ph) gives Fe₄Au₂C(CO)₁₂(PR₃)₂; the formation of the latter involves attack at the carbido centre by the gold phosphine group. Both neutral carbido species were characterised by single-crystal X-ray analyses.
