In the title triangulo-triruthenium compound, [Ru(3)(C(21)H(21)As)(CO)(11)], one equatorial carbonyl group has been substituted by the monodentate arsine ligand, leaving one equatorial and two axial carbonyl substituents on the Ru atom. The remaining two Ru atoms each carry two equatorial and two axial terminal carbonyl ligands. The three arsine-substituted phenyl rings make dihedral angles of 73.2 (2), 71.0 (2) and 75.3 (2)° with each other. In the crystal packing, mol-ecules are stacked down the b axis and each mol-ecule is stabilized by an intra-molecular C-H⋯O hydrogen bond.
在标题化合物三角三钌化合物[Ru(3)(C(21)H(21)As)(CO)(11)]中，一个赤道面羰基已被单齿砷配体取代，钌原子上留下一个赤道面羰基和两个轴向羰基取代基。其余两个钌原子各自带有两个赤道面和两个轴向端羰基配体。三个砷取代的苯环彼此间的二面角分别为73.2 (2)、71.0 (2)和75.3 (2)°。在晶体堆积中，分子沿b轴堆积，每个分子通过分子内C—H⋯O氢键得以稳定。
