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-HO hydrogen bonds. The crystal packing is stabilized by intermolecular O-HO, O-HN and O-HCl 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).
The title compound was studied during efforts to obtain potential ferroelectric phase-transition materials. For general background to ferroelectric metal-organic frameworks, see: Fu et al. (2009); Ye et al. (2006); Zhang et al. (2008, 2010).
