Nonacarbonyl-1κ3C,2κ3C,3κ3C-μ-bis(diphenylarsino)methane-1:2κ2As:As'-[tris(2-chloroethyl) phosphite-3κP]-triangulo-triruthenium(0)
Abstract
In the title triangulo-triruthenium(0) compound, [Ru3(C25H22As2)(C6H12Cl3O3P)(CO)9], the bis(diphenylarsino)methane ligand bridges an Ru—Ru bond and the monodentate phosphine ligand bonds to the third Ru atom. Both the arsine and phosphine ligands are equatorial with respect to the Ru3 triangle. In addition, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. In the crystal packing, the molecules are linked by intermolecular C—H...O hydrogen bonds into a three-dimensional framework. Weak intermolecular C—H...π interactions further stabilize the crystal structure.
