Abstract:	The complexes RuC(CCPh)=CPhC(CCPh)=CPh(CO)₃(NMe₃) (3), Ru₂μ-C(CCPh)=CPhC(CCPh)=CPh(CO)₆ (1), Ru₂μ-C(CCPh)=CPh]₂CO(CO)₆ (2), Ru₃(μ₃-PhC₂CCPh)(μ-CO)(CO)₉ (4) and Ru₄(μ₄-PhC₂CCPh)(CO)₁₂ (5) have been isolated from reactions between PhC₂C₂Ph and Ru₃(CO)₁₂ or RU₃(CO)₁₀(NCMe)₂. The molecular structures of complexes 1, 2, 3 and 5 have been determined from single-crystal X-ray studies. All complexes have precedents in similar products obtained from reactions involving mono-ynes; in the present cases, each alkyne fragment retains a phenylethynyl (PhCC---) group as a non-coordinated substituent.
