We have used the elimination of AuX(PR₃) (X=halide, R=Ph, tol) that occurs in reactions of alkynylgold(I)aaaphosphine complexes with M₃(aa-H)₃ (aa₃-CBr) (CO)₉ (M=Ru, Os) to prepare the complexes M₃(aa-H)₃(aa₃-CCCR)(CO)₉ [M=Ru, R=Ph 2, CCSiMe₃ 3, Fc 4, CCFc 6-Ru, CC[Ru(PPh₃)₂Cp] 8; M=Os, R=CCFc 6-Os, CCCCFc 7], Fcaaa{(aa₃-CCC)Ru₃(aa-H)₃(CO)₉}₂5, and bis-cluster-capped carbon chain complexes {M₃(aa-H)₃(CO)₉}₂{aa₃:aa₃-C(CC)_nC} (M=Ru, n
