title: [μ-Bis(diphenyl-phosphan-yl)ethane-1:2κP:P']nona-carbonyl-1κC,2κC,3κC-[tris-(4-(meth-oxy-phen-yl)arsane-3κAs]-triangulo-triruthenium(0) chloro-form monosolvate.
abstract: The asymmetric unit of the title triangulo-triruthenium compound, [Ru(3)(C(21)H(21)AsO(3))(C(26)H(24)P(2))(CO)(9)]·CHCl(3), consists of one mol-ecule of the triangulo-triruthenium complex and one chloro-form solvent mol-ecule. The bis(diphenyl-phosphan-yl)ethane ligand bridges an Ru-Ru bond and the monodentate arsane ligand bonds to the third Ru atom. Both the arsane and phosphine ligands are equatorial with respect to the Ru(3) triangle. Additionally, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. The three arsane-substituted benzene rings make dihedral angles of 52.72 (19), 63.03 (19) and 88.19 (19)° with each other. The dihedral angles between the two benzene rings are 85.8 (2) and 89.2 (2)° for the two diphenyl-phosphanyl groups. In the crystal, mol-ecules are linked together into a three-dimensional network via inter-molecular C-H⋯O hydrogen bonds. Weak inter-molecular C-H⋯π inter-actions further stabilize the crystal structure.
