Dichlorido[1-(2-methyl-benz-yl)-3-(?6-2,4, 6-trimethyl-benz-yl)-1H-2,3-dihydro-benzimidazol-2-yl-idene]ruthenium(II) dichloro-methane solvate

The title complex, [RuClCl]·CHl 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 CCHarene group by a CHbridge. 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
