title: 1-Benzyl-3-methyl-imidazolium chloride 0.25-hydrate.
abstract: The asymmetric unit of the title compound, C(11)H(13)N(2) (+)·Cl(-), contains two independent ion pairs and and half a solvent water mol-ecule (m site symmetry for the O atom). The imidazole ring is oriented at dihedral angles of 66.61 (3) and 89.17 (3)° with respect to the aromatic ring in the two cations. In the crystal, O-H⋯(O,Cl) hydrogen bonds and π-π stacking inter-actions between the imidazole ring of one mol-ecule and the aromatic ring of another [perpendicular distance = 3.4 (4) Å] link the mol-ecules.
