rac-cis,cis-Dicarbonyl­dichlorido{1-[2-(diphenyl­phosphan­yl)benz­yl]-3-mesityl­imidazol-2-yl­idene}ruthenium(II) dichloro­methane monosolvate

The Ru^II atom in the title compound, [RuCl₂(C₃₁H₂₉N₂P)(CO)₂]·CH₂Cl₂, exhibits a distorted octahedral coordination environment. The bond angles of the cis substituents at the Ru^II atom range from 82.72 (9) to 97.20 (3)°. This mol­ecule is of inter­est in the field of catalytic transfer hydrogenation.

rac-cis-Dicarbonyl­chlorido{1-[2-(diphenyl­phosphanyl-κP)benz­yl]-3-(phenyl-κC¹)imidazol-2-yl­idene-κC²}ruthenium(II) dichloro­methane monosolvate

In the title compound, [Ru(C₂₈H₂₂N₂P)Cl(CO)₂]·CH₂Cl₂, the Ru^II atom exhibits a distorted octa­hedral coordination geometry. The N-phenyl group of the ligand has undergone orthometalation; as a result, the tridentate phosphane-functionalized N-heterocyclic carbene ligand is coordinating in a meridional fashion. This complex is of inter­est with respect to transfer hydrogenation catalysis and also provides an example of C—H activation behavior in late transition metal complexes. The dichloro­methane solvent mol­ecule is disordered over two sets of sites with an occupancy ratio of 0.873 (14):0.127 (14).
