The title compound, C15H13N4+·ClO4−, comprises a nonplanar 1-(2-cyanoethyl)-2-(2-pyridyl)-1H,3H-benzimidazol-3-ium cation [dihedral angle between the imidazole and pyridine rings = 22.5 (8)°] and a perchlorate anion. The cation is formed by protonation of the N atom of the benzimidazole ring. A charged N—H...O hydrogen bond connects the anion and cation, and intermolecular C—H...O and C—H...N interactions contribute to the crystal packing.
