title: 2-(2-Pyrrolidinio)-1H-benzimidazol-3-ium dinitrate.
abstract: In the title compound, C(11)H(15)N(3) (2+)·2NO(3) (-), one of the imidazole N atoms and the N atom of the pyrrolidine ring are protonated. The pyrrolidine ring adopts an envelope conformation, with the C atom carrying the benzoimidazolium substituent as the flap atom. In the crystal structure, cations and anions are linked through N-H⋯O hydrogen bonds, forming chains that run parallel to the c axis.
