Undeca-carbonyl-1?C,2?C,3?C-(triethyl phosphite-1?P)-triangulo-triruthenium(0).

ABSTRACT: In the title triangulo-triruthenium compound, [Ru(3)(C(6)H(15)O(3)P)(CO)(11)], each Ru atom has distorted octa-hedral coord-ination geometry. The monodentate phosphine ligand is equatorially coordinated to one Ru atom, leaving one equatorial and two axial carbonyl substituents on the Ru atom. Each of the remaining two Ru atoms carries two equatorial and two axial carbonyl groups. In the crystal, mol-ecules are linked into an inversion dimer by a pair of inter-molecular C-H?O hydrogen bonds and the dimers are stacked along the b axis.
