2-Amino-6-nitro-1H-benzoimidazol-3-ium chloride

Abstract

In the cation of the title compound, C7H7N4O2+·Cl−, the benzimidazole ring system is planar with a maximum deviation of −0.019 (3) Å. In the crystal structure, C—H...Cl, N—H...Cl, and N—H...Cl interactions link the molecules into a two-dimensional network. π–π contacts between benzimidazole rings [centroid–centroid distances = 3.928 (1) and 3.587 (1) Å] may further stabilize the structure.
