title: (1H-Benzimidazol-2-yl)methanaminium perchlorate-18-crown-6-water (1/1/1).
abstract: The crystal structure of the title compound C(8)H(10)N(3) (+)·ClO(4) (-)·C(12)H(24)O(6)·H(2)O, consists of an organic (1H-benzimidazol-2-yl)methanaminium cation, an inorganic ClO(4) (-) anion, one 18-crown-6 mol-ecule and one water mol-ecule. In the crystal, the cations and 18-crown-6 mol-ecules are linked by N-H⋯O hydrogen bonds. The crystal packing is stabilized by inter-molecular O-H⋯O, O-H⋯N and O-H⋯Cl hydrogen bonds between anions and the water mol-ecules. 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).
