ABSTRACT: The title compound, [Os(3)(C(25)H(22)As(2))(CO)(10)], contains a triangle of singly bonded Os atoms; both arsine ligands are equatorial with respect to the Os(3) triangle. Each arsine-substituted Os atom bears one equatorial and two axial terminal carbonyl ligands, whereas the unsubstituted Os atom bears two equatorial and two axial terminal carbonyl ligands. The dihedral angles between the two benzene rings in the diphenyl-arsino groups are 67.42?(16) and 61.99?(16)°. In the crystal, mol-ecules are linked via C-H?O hydrogen bonds into zigzag chains propagating along [010].

Project description:The asymmetric unit of the title triangulo-triruthenium compound, [Ru(3)(C(25)H(22)As(2))(C(19)H(17)P)(CO)(9)], consists of two crystallographically independent mol-ecules of the triangulo-triruthenium complex, A and B. 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. With regard to the three phosphine-substituted rings, the benzyl ring makes dihedral angles of 41.0?(3) and 43.9?(3)° with the other two benzene rings in mol-ecule A; these angles are 49.8?(3) and 56.8?(3)° in mol-ecule B. The dihedral angles between the two benzene rings are 76.1?(3) and 88.2?(3)° for the two diphenyl-arsino groups in mol-ecule A and 71.3?(3) and 78.1?(3)° in mol-ecule B. In the crystal packing, mol-ecules are linked into chains via inter-molecular C-H?O hydrogen bonds. Weak inter-molecular C-H?? inter-actions further stabilize the crystal structure.
