1-Benzyl-3-methylimidazolium chloride 0.25-hydrate

Abstract

The asymmetric unit of the title compound, C11H13N2+·Cl−, contains two independent ion pairs and and half a solvent water molecule (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 interactions between the imidazole ring of one molecule and the aromatic ring of another [perpendicular distance = 3.4 (4) Å] link the molecules.
