1,3-Difurfurylbenzimidazolium chloride monohydrate

Abstract

The title compound, C17H15N2O2+center dot Cl-center dot H2O, 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)degrees with respect to each other, and make dihedral angles of 73.92 (12) and 72.58 (13)degrees with respect to the benzimidazole ring. O-H center dot center dot center dot Cl, C-H center dot center dot center dot O and C-H center dot center dot center dot Cl hydrogen bonds and C-H center dot center dot center dot pi interactions contribute to the stabilization of the crystal structure. Furthermore, there is a pi-pi interaction between adjacent five- and six-membered rings of the benzimidazole groups [centroid-centroid distance = 3.5305 (8) angstrom
