Bis{[μ-bis-(diphenyl-arsino)methane-1:2κAs:As']nona-carbonyl-1κC,2κC,3κC-[tris-(4-chloro-phen-yl)phosphine-3κP]-triangulo-triruthenium(0)} chloro-form monosolvate.

ABSTRACT: The asymmetric unit of the title triangulo-triruthenium compound, 2[Ru(3)(C(25)H(22)As(2))(C(18)H(12)Cl(3)P)(CO)(9)]·CHCl(3), consists of two mol-ecules (A and B) of the triangulo-triruthenium complex and one mol-ecule of chloro-form solvent. The bis-(diphenyl-arsino)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 Ru(3) triangle. In addition, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. The three phosphine-substituted benzene rings make dihedral angles of 73.5 (3), 57.2 (3) and 75.7 (3)° with each other in mol-ecule A, while these angles are 60.7 (3), 86.8 (3) and 54.9 (3)° in mol-ecule B. The dihedral angles between the two benzene
