Bruce, M.Skelton, B.White, A.Zaitseva, N.2007-02-252007-02-251996Australian Journal of Chemistry: an international journal for chemical science, 1996; 1996: 49(1):155-1580004-9425http://hdl.handle.net/2440/4393The molecular structures M3(μ3-η2-PhC2C≡CPh)(μ-CO)(CO)9 (M = Ru and Os) are described: these complexes are similar to several mono-alkyne derivatives, with one C≡C triple bond of the diyne ligand attached in the 2η1,η2-(||) mode to the closed triangular M3 core. The M-M edge parallel to the complexed C≡C triple bond is asymmetrically bridged by a CO ligand; the coordination about each M atom is completed by three terminal CO ligands.
