trans-1,2-Bis(1-methylbenzimidazol-2-yl)cyclohexane monohydrate

R. T. Stibrany, H. J. Schugar and J. A. Potenza

Abstract: Chiral molecules of the title compound, C₂₂H₂₄N₄·H₂O, have approximate twofold symmetry, essentially planar benzimidazole fragments, and a ladder-like appearance in profile, with the benzimidazole planes exhibiting a dihedral angle of 68.75 (4)°. Geometric parameters are consistent with those of comparable species containing benzimidazole or cyclohexyl fragments. Adventitious water molecules of solvation form strong O-HN(imine) hydrogen bonds to yield infinite 2₁ columns along the c-axis direction. The columns are related by glide-plane symmetry operations and are linked by C-H interactions to yield racemic crystals.
