Descripción
Sumario: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 diphenyl­arsino groups are 67.42 (16) and 61.99 (16)°. In the crystal, mol­ecules are linked via C—H⋯O hydrogen bonds into zigzag chains propagating along [010].
