Abstract

The action of CO on the pentanuclear carbido cluster [Ru ₅C(CO)¹⁴(AuPR₃)₂] [PR₃ = PEt₃ (1), PPh₃ (2), PMe₂Ph (3)] (80 atm, 60°C) affords the tetranuclear carbido cluster [Ru₄C(CO) ₁₂(AuPR₃)₂] [PR₃ = PEt₃ (4), PPh₃ (5), PMe₂Ph (6)], which exhibits a carbide-centred, 'butterfly' Ru₄C core with both the 'wing-tip' and 'hinge' Ru atoms bridged by AuPR₃ groups; the 'hinge' bridging AuPR₃ group may be replaced by reaction with I₂ or Hl to give [Ru₄C(CO)₁₂(I)(AuPR₃)] [PR₃ = PEt₃ (7), PPh₃ (8)] and [Ru₄(H)C(CO) ₁₂(AuPR₃)] [PR₃ = PEt₃ (9), PPh ₃ (10)], respectively, and the subsequent reaction of (9) and (10) with [BH₄]^- removes the remaining AuPR₃ group, acidification affording the tetraruthenium carbide [Ru₄(H) ₂C(CO)₁₂] (11).
