The title complex, [RuCl2(C25H26N2)]center dot CH2Cl2, is best thought of as containing an octahedrally coordinated Ru center with the arene occupying three sites. Two Ru-Cl bonds and one Ru-carbene bond complete the distorted octahedron. The carbene portion of the ligand is a benzimidazole ring. This ring is connected to the C6H2(CH3)(3) arene group by a CH2 bridge. This leads to a system with very little apparent strain. A dichloromethane solvent molecule completes the crystal structure. Further stabilization is accomplished via C-center dot center dot center dot N and C-H center dot center dot center dot Cl interactions.
