Abstract
The complexes RuC(Ctriple bond; length as m-dashCPh)=CPhC(Ctriple bond; length as m-dashCPh)=CPh(CO)3(NMe3) (3), Ru2μ-C(Ctriple bond; length as m-dashCPh)=CPhC(Ctriple bond; length as m-dashCPh)=CPh(CO)6 (1), Ru2μ-[C(Ctriple bond; length as m-dashCPh)=CPh]2CO(CO)6 (2), Ru3(μ3-PhC2Ctriple bond; length as m-dashCPh)(μ-CO)(CO)9 (4) and Ru4(μ4-PhC2Ctriple bond; length as m-dashCPh)(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 (PhCtriple bond; length as m-dashC---) group as a non-coordinated substituent.
