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.enCrystal structuresRuthenium complexes1,3-Diyne complexesCarbonyl complexesCluster complexesJournal article003000270310.1016/S0020-1693(96)05219-X66709Bruce, M.
