Abstract
The asymmetric unit of the title triangulo-triruthenium compound, Ru-3(CO)(9)(mu-Ph2AsCH2AsPh2)(P[OCH(CH3)(2)](3)) or [Ru-3(C25H22As2)(C9H21O3P)(CO)(9)], contains two molecules of the triangulo-triruthenium complex. The bis(diphenylarsanyl) methane ligand bridges an Ru-Ru bond and the monodentate phosphite ligand binds to the third Ru atom. Both the arsine and phosphite ligands are equatorial with respect to the Ru-3 triangle. Additionally, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. The dihedral angles between the pairs of benzene rings bound to individual As atoms are 85.67 (8) and 75.91 (8) in the first independent molecule and 74.64 (8) and 70.76 (9) in the second. In the crystal, molecules are linked into a three-dimensional framework by intermolecular C-H center dot center dot center dot O hydrogen bonds.
