摘要

The reaction between RuCl(PPh₃)₂Cp^* and {Cu(CCPh)}_n in refluxing benzene afforded Ru₂Cu₂(C₂Ph)₅H₂(Cl)(PPh₃)Cp^*₂, which contains an unusual tetramer of the phenylethynyl group which interacts with an Ru…Cu…Cu…Ru chain. The second Ru atom is part of a ruthenocenyl moiety which interacts weakly with the second Cu atom, and bears a vinylidene which bridges an Ru–Cu vector. The structure of a second modification of Ru(CCPh)(CO)(PPh₃)Cp^* is also reported.
