1,3-Difurfurylbenzimidazolium chloride monohydrate

The title compound, C(17)H(15)N(2)O(2) (+)·Cl(−)·H(2)O, was synthesized from benzimidazole and furfryl chloride in dimethyl­formamide. The cationic benzimidazolium ring is connected to two furan rings via methyl­ene 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 inter­actions contribute to the stabilization of the crystal structure. Furthermore, there is a π–π inter­action between adjacent five- and six-membered rings of the benzimidazole groups [centroid–centroid distance = 3.5305 (8) Å].
