Abstract: The title complex, [RuCl₂(C₂₅H₂₆N₂)]·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-HN and C-HCl interactions.
