The 8H10N3+·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).

2-(1H-benzimidazol-2-yl)-ethylamine (0.09 g) and an excess of perchloric acid (0.302 g) were dissolved in methanol. Then, 18-crown-6 (0.528 g) was added to the mixture. The precipitate was filtered and washed with a small amount of methanol. Single crystals suitable for X-ray diffraction were obtained by slow evaporation of a methanol solution at room temperature over two days.
H atoms were placed in calculated positions (N—H = 0.90 Å and C—H = 0.97 Å for Csp2 atoms), assigned fixed Uiso values [Uiso = 1.2Ueq(Csp2) and 1.5Ueq( N)] and allowed to ride. The H1WA and H1WB on the O1W were refined freely along their isotropic displacement parameters. The disordered atoms O8 and C2 were split over two sites, the occupancies of which were refined with anisotropics models to a final occupancy of 0.60 (2)/0.40 (2).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The study of ferroelectric materials has received much attention and some materials have predominantly dielectric–ferroelectric performance (Ye et al., 2006; Fu et al., 2009; Zhang et al. 2010; Zhang et al., 2008). As a part of our work to obtain potential ferroelectric phase-transition materials, we report here the crystal structure of title compound. Unluckily, the title compound has no dielectric anomalies in the temperature range 93–453 K, suggesting that it might be only a paraelectric.
The asymmetric unit of the title compoundis is shown in Fig. 1.The structure of the title compound C8H10N3+.ClO4- .C12H24O6.H2O, consists of an organic 2-(1H-benzimidazol-2-yl)-ethylammonium cation, and inorganic ion (ClO4)- one 18-crown-6 molecule and one water molecule. In the asymmetric unit the cations and the 18-crown-6 molecules are linked by by N—H···O hydrogen bonds. The crystal packing is stabilized by intermolecular O—H···O and O—H···Cl hydrogen bonds between anions and water molecules, Table 1. The C2 and O8 atoms are disordered with ocupation factors of 0.60 (2)/0.40 (2) respectively.
