1-(4-Chlorobenzyl)-3-[2-(Pyrrolidinium-1-yl)-Ethyl]benzimidazolium Dichloride Monohydrate

Abstract

The title compound, C<inf>20</inf>H<inf>26</inf>Cl<inf>3</inf>N <inf>3</inf>O, was synthesized from 1-(4-chlorobenzyl)benzimidazole and 1-(2-chloroethyl)pyrrolidine hydrochloride in dimethylformamide. The dihedral angle between the benzene ring and the benzimidazole ring system is 68.33 (8)°. The five-membered pyrrolidine ring has a slightly distorted envelope conformation. The crystal structure is stabilized by O-H⋯Cl, C-H⋯Cl, N-H⋯Cl and C-H⋯O hydrogen bonds. © 2007 International Union of Crystallography. All rights reserved.
