[μ-Bis(diphenylarsino)methane-1:2κ2 As:As′]nonacarbonyl-1κ3 C,2κ3 C,3κ3 C-tricyclohexylphosphine-3κP-triangulo-triruthenium(0)
In the title triangulo-triruthenium compound, [Ru3(C25H22As2)(C18H33P)(CO)9], the bis(diphenylarsino)methane ligand bridges an Ru—Ru bond and the monodentate phosphine ligand bonds to the third Ru atom. Both the phosphine and arsine ligands are equatorial with respect to the Ru3 triangle. In addition, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. All three cyclohexane rings are disordered over two positions with site occupancies of 0.628 (6) and 0.372 (6). The mean planes of these three phosphine-substituted cyclohexane rings make dihedral angles of 53.0 (8), 68.3 (6) and 89.9 (7)° (major components), and 46.7 (14), 41.3 (11) and 75.8 (10)° (minor components) with each other. The dihedral angles between the two phenyl rings are 85.0 (2) and 88.1 (2)° for the two diphenylarsino groups. Two cyclohexane rings adopt a chair conformation whereas the other adopts a slightly twisted chair conformation for the major components; these conformations are similiar for the minor components. Intramolecular C—H⋯O hydrogen bonds stabilize the molecular structure. In the crystal packing, the molecules are linked together into chains via intermolecular C—H⋯O hydrogen bonds down the a axis. Weak intermolecular C—H⋯π interactions further stabilize the crystal structure
