In the title triangulo-triruthenium compound, [Ru(3)(C(25)H(22)As(2))(C(18)H(15)Sb)(CO)(9)], the bis-(diphenyl-arsino)methane ligand bridges an Ru-Ru bond and the monodentate stibine ligand bonds to the third Ru atom. Both the stibine and arsine ligands are equatorial with respect to the Ru(3) triangle. Additionally, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. The three stibine-substituted phenyl rings make dihedral angles of 84.3 (3), 80.4 (3) and 70.5 (3)° with each other. The dihedral angles between the two phenyl rings are 85.9 (3) and 75.2 (3)° for the two diphenyl-arsine groups. In the crystal packing, mol-ecules are linked into chains down the c axis via inter-molecular C-H⋯O hydrogen bonds. Weak inter-molecular C-H⋯π inter-actions further stabilize the crystal structure.
在标题化合物三角-三钌化合物[Ru(3)(C(25)H(22)As(2))(C(18)H(15)Sb)(CO)(9)]中，双（二苯基砷基）甲烷配体桥连一个Ru-Ru键，单齿锑配体与第三个Ru原子键合。锑配体和砷配体相对于Ru(3)三角形均处于赤道平面。此外，每个Ru原子带有一个赤道平面和两个轴向末端羰基配体。三个被锑取代的苯环彼此间的二面角分别为84.3 (3)、80.4 (3)和70.5 (3)°。两个二苯基砷基团的两个苯环之间的二面角分别为85.9 (3)和75.2 (3)°。在晶体堆积中，分子通过分子间C-H⋯O氢键沿c轴连接成链。弱分子间C-H⋯π相互作用进一步稳定了晶体结构。
