Bis{[μ-bis-(diphenyl-arsino)methane-1:2κAs:As']nona-carbonyl-1κC,2κC,3κC-[tris-(4-methoxy-phen-yl)arsine-3κAs]-triangulo-triruthenium(0)} dichloro-methane solvate.

ABSTRACT: The asymmetric unit of the title triangulo-triruthenium compound, 2[Ru(3)(C(25)H(22)As(2))(C(21)H(21)AsO(3))(CO)(9)]·CH(2)Cl(2), contains one triangulo-triruthenium complex mol-ecule and one half of the dichloro-methane solvent. The dichloro-methane solvent lies across a crystallographic inversion center leading to the mol-ecule being disordered over two positions of equal occupancy. The bis-(diphenyl-arsino)methane ligand bridges an Ru-Ru bond and the monodentate arsine ligand bonds to the third Ru atom. Both the 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 trimethoxy-phenyl-arsino benzene rings make dihedral angles of 83.01 (8), 65.81 (8) and 76.20 (8)° with each other. The
