1‐Benz­yl‐3‐[2‐(1‐piperidinio)eth­yl]benzimidazolium dichloride monohydrate

The title compound, C21H27N32+·2Cl−·H2O, was synthesized from 1-benzyl­benzimidazole and 2-chloro­ethyl­piperidine hydro­chloride in dimethyl­formamide. In the cation, the benzimidazole ring is connected to the piperidine ring by an ethyl­ene group. The crystal structure is stabilized by O—H⋯Cl, N—H⋯Cl, C—H⋯O and C—H⋯Cl hydrogen-bonding inter­actions.
