[μ-Bis(di-o-tolylphosphanyl)methane-1:2κ2P:P′]decacarbonyl-1κ3C,2κ3C,3κ4C-triangulo-triruthenium(0)–methanol (8/1)
Abstract
The asymmetric unit of the title compound, [Ru3(C29H30P2)(CO)10].1/8CH3OH, contains two triangulo-triruthenium molecules with similar configurations and a methanol solvent molecule (fractional site occupancy for the latter = 0.25). The bis(di-o-tolylphosphanyl)methane ligand bridges an Ru—Ru bond and its P atoms are equatorial with respect to the Ru3 triangle. The phosphine-substituted Ru atoms each bear one equatorial and two axial terminal carbonyl ligands whereas the unsubstituted Ru atom carries two equatorial and two axial terminal carbonyl ligands. The dihedral angles between the two benzene rings attached to each P atom are 76.26 (13) and 74.76 (15)° for the first molecule and 77.21 (13) and 75.68 (14)° for the second. In the crystal, molecules are linked into [001] chains via intermolecular C—H...O hydrogen bonds. Weak intermolecular C—H...π interactions also occur.
