[μ-Bis(diphenyl-arsino)methane-1:2κAs:As'][bis-(4-methoxy-phen-yl)phenyl-phosphine-3κP]-nona-carbonyl-1κC,2κC,3κC-triangulo-tri-ruthenium(0) dichloro-methane 0.15-solvate.

ABSTRACT: The asymmetric unit of the title triangulo-triruthenium compound, [Ru(3)(C(25)H(22)As(2))(C(20)H(19)O(2)P)(CO)(9)]·0.15CH(2)Cl(2), contains one mol-ecule of the triangulo-triruthenium complex and one partially occupied dichloro-methane solvent mol-ecule. 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 three phospho-rus-bound benzene rings make dihedral angles of 72.7 (3), 80.9 (3) and 70.8 (2)°
