Abstract

Treatment of carbido cluster Ru₆(μ₆-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)Ru₆(μ₆-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 Ru₃ metal triangle of central Ru₆(μ₆-C) framework. Thermolysis of 1 in toluene leads to the formation of a toluene substituted complex (C₅Me₅)W(O)₂(CCPh)Ru₆(μ₆-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.
