Abstract
The asymmetric unit of the title triangulo-triruthenium compound, [Ru3(C26H24P2)(C18H15Sb)(CO)9], consists of two crystallographically independent molecules, A and B. The bis(diphenylphosphanyl)ethane ligand bridges an Ru—Ru bond and the monodentate stibine ligand bonds to the third Ru atom. Both the stibine and phosphine ligands are equatorial with respect to the Ru3 triangle. Additionally, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. The three stibine-substituted benzene rings make dihedral angles of 38.7 (3), 71.5 (3) and 70.0 (3)° with each other in molecule A whereas these angles are 83.9 (3), 88.2 (3) and 56.8 (3)° in molecule B. Similarly, the dihedral angles between the two benzene rings are 80.7 (3) and 87.6 (3)° for the two diphenylphosphanyl groups in molecule A and 84.0 (3) and 72.6 (4)° in molecule B. In the crystal, molecules are linked into tetramers via intermolecular C—H⋯O hydrogen bonds. Weak intermolecular C—H⋯π interactions further stabilize the crystal structure.
