(1H-Benzimidazol-2-yl)methanaminium perchlorate–18-crown-6–water (1/1/1)

The crystal structure of the title compound C₈H₁₀N₃⁺·ClO₄⁻·C₁₂H₂₄O₆·H₂O, consists of an organic (1H-benzimidazol-2-yl)methanaminium cation, an inorganic ClO₄⁻ anion, one 18-crown-6 mol­ecule and one water mol­ecule. In the crystal, the cations and 18-crown-6 mol­ecules are linked by N—H...O hydrogen bonds. The crystal packing is stabilized by inter­molecular O—H...O, O—H...N and O—H...Cl hydrogen bonds between anions and the water mol­ecules. One 18-crown-6 C atom and a perchlorate O atom are disordered; both have an occupancy factor ratio of 0.60 (2) and 0.40 (2).
