Abstract

The title complex, [RuCl(2)(C(25)H(26)N(2))]·CH(2)Cl(2), is best thought of as containing an octa-hedrally coordinated Ru center with the arene occupying three sites. Two Ru-Cl bonds and one Ru-carbene bond complete the distorted octa-hedron. The carbene portion of the ligand is a benzimidazole ring. This ring is connected to the C(6)H(2)(CH(3))(3) arene group by a CH(2) bridge. This leads to a system with very little apparent strain. A dichloro-methane solvent mol-ecule completes the crystal structure. Further stabilization is accomplished via C-H⋯N and C-H⋯Cl interactions.
