In the title triangulo-triruthenium compound, [Ru(3)(C(25)H(22)As(2))(C(21)H(21)P)(CO)(9)], the bis-(diphenyl-arsino)methane ligand bridges a 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. Additionally, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. The three phenyl rings of the phosphine make dihedral angles of 86.89 (19), 82.1 (2) and 63.0 (2)° with each other. The dihedral angles between the two phenyl rings are 73.8 (2) and 82.2 (3)° for the two diphenyl-arsino groups. An intra-molecular C-H⋯O hydrogen bond stabilizes the mol-ecular structure. In the crystal packing, mol-ecules are linked into chains down the b axis via inter-molecular C-H⋯O hydrogen bonds.
在标题为三角三钌化合物[Ru(3)(C(25)H(22)As(2))(C(21)H(21)P)(CO)(9)]中，双（二苯基砷基）甲烷配体桥连一个Ru-Ru键，单齿膦配体与第三个Ru原子键合。膦和砷配体相对于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。膦的三个苯环彼此间的二面角分别为86.89 (19)、82.1 (2)和63.0 (2)°。两个二苯基砷基的两个苯环之间的二面角分别为73.8 (2)和82.2 (3)°。分子内的C-H⋯O氢键使分子结构稳定。在晶体堆积中，分子通过分子间的C-H⋯O氢键沿b轴连接成链。
