2010302010065 ; 化學系 ; Treatment of carbido cluster Ru-6(mu(6)-C)(CO)(17) with 3 equiv. of Me3NO, followed by addition of high-valent acetylide complex (C5Me5)W(O)(2)(CCPh), affords a novel heterometallic cluster complex with formula (C5Me5)W(O)(2)(CCPh)Ru-6(lambda(6)-C)(CO)(14) (1). The (C5Me5)W(O)(2)(CCPh) fragment in this molecule, which serves as a six-electron-donor ligand, uses one of the W-O multiple bonds and the acetylide C-C triple bond to fill three adjacent coordination sites on the Ru-3 metal triangle of central Ru-6(mu(6)-C) framework. Thermolysis of 1 in toluene leads to the formation of a toluene substituted complex (C5Me5)W(O)(2)(CCPh)Ru-6(mu(6)-C)(CO)(11)(C7H8) (2) which exhibits the same metal core arrangement as its precursor 1. In addition, the X-ray structural analysis reveals the evidence for extensive hydrogen bonding between the terminal oxo ligand and the methanol solvate present in the unit cell.
