In the title triangulo-triruthenium compound, [Ru(3)(C(25)H(22)(As(2))(C(18)H(12)F(3)P)(CO)(9)], 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. Additionally, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. The three phosphine-substituted rings make dihedral angles of 87.76 (13), 57.43 (13) and 73.81 (12)° with each other. The dihedral angles between the pairs of rings are 69.78 (14) and 83.38 (16)° for the two diphenyl-arsino groups. In the crystal packing, mol-ecules are linked by inter-molecular C-H⋯F and C-H⋯O hydrogen bonds, forming two-dimensional planes parallel to the ab plane. These planes are also linked by inter-molecular C-H⋯O hydrogen bonds into a three-dimensional framework. Inter-molecular C-H⋯π inter-actions further stabilize the crystal structure.
在标题为三角-三钌化合物[Ru(3)(C(25)H(22)(As(2))(C(18)H(12)F(3)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。三个膦取代环彼此之间的二面角分别为87.76 (13)、57.43 (13)和73.81 (12)°。两个二苯基砷基之间的环对二面角分别为69.78 (14)和83.38 (16)°。在晶体堆积中，分子通过分子间C-H⋯F和C-H⋯O氢键相连，形成平行于ab平面的二维平面。这些平面也通过分子间C-H⋯O氢键连接成三维框架。分子间C-H⋯π相互作用进一步稳定了晶体结构。
