[?-Bis(diphenyl-phosphan-yl)ethane-1:2?P:P']nona-carbonyl-1?C,2?C,3?C-(triphenyl-stibine-3?Sb)-triangulo-triruthenium(0).

ABSTRACT: The asymmetric unit of the title triangulo-triruthenium compound, [Ru(3)(C(26)H(24)P(2))(C(18)H(15)Sb)(CO)(9)], consists of two crystallographically independent mol-ecules, A and B. The bis-(diphenyl-phosphan-yl)ethane ligand bridges an Ru-Ru bond and the monodentate stibine ligand bonds to the third Ru atom. Both the stibine and phosphine 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 stibine-substituted benzene rings make dihedral angles of 38.7?(3), 71.5?(3) and 70.0?(3)° with each other in mol-ecule A whereas these angles are 83.9?(3), 88.2?(3) and 56.8?(3)° in mol-ecule B. Similarly, the dihedral angles between the two benzene rings are 80.7?(3) and 87.6?(3)° for the two diphenyl-phosphanyl groups in mol-ecule A and 84.0?(3) and 72.6?(4)° in mol-ecule B. In the crystal, mol-ecules are linked into tetra-mers via inter-molecular C-H?O hydrogen bonds. Weak inter-molecular C-H?? inter-actions further stabilize the crystal structure.
