1,3-Difurfurylbenzimidazolium Chloride Monohydrate

Abstract

The title compound, C<inf>17</inf>H<inf>15</inf>N<inf>2</inf>O<inf>2</inf> +·Cl-·H<inf>2</inf>O, was synthesized from benzimidazole and furfryl chloride in dimethyl-formamide. The cationic benzimidazolium ring is connected to two furan rings via methyl-ene bridges. The furan rings make dihedral angle of 79.09 (18)° with respect to each other, and make dihedral angles of 73.92 (12) and 72.58 (13)° with respect to the benzimidazole ring. O - H⋯Cl, C - H⋯O and C - H⋯Cl hydrogen bonds and C - H⋯π inter-actions contribute to the stabilization of the crystal structure. Furthermore, there is a π-π inter-action between adjacent five- and six-membered rings of the benzimidazole groups [centroid-centroid distance = 3.5305 (8) Å]. © 2009 Akkurt et al.
