[μ-Bis(diphenylphosphanyl)ethane-1:2κ²P:P′]nonacarbonyl-1κ³C,2κ³C,3κ³C-[tris(4-(methoxyphenyl)arsane-3κAs]-triangulo-triruthenium(0) chloroform monosolvate

Abstract

[l-Bis(diphenylphosphanyl)ethane-1:2j 2 P:P Key indicators: single-crystal X-ray study; T = 100 K; mean (C-C) = 0.006 Å; R factor = 0.067; wR factor = 0.108; data-to-parameter ratio = 24.0.The asymmetric unit of the title triangulo-triruthenium compound, [Ru 3 (C 21 H 21 AsO 3 )(C 26 H 24 P 2 )(CO) 9 ]ÁCHCl 3 , consists of one molecule of the triangulo-triruthenium complex and one chloroform solvent molecule. The bis-(diphenylphosphanyl)ethane ligand bridges an Ru-Ru bond and the monodentate arsane ligand bonds to the third Ru atom. Both the arsane 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 arsane-substituted benzene rings make dihedral angles of 52.72 (19), 63.03 (19) and 88.19 (19) with each other. The dihedral angles between the two benzene rings are 85.8 (2) and 89.2 (2) for the two diphenylphosphanyl groups. In the crystal, molecules are linked together into a threedimensional network via intermolecular C-HÁ Á ÁO hydrogen bonds. Weak intermolecular C-HÁ Á Á interactions further stabilize the crystal structure.
