Part of the packing of O—H⋯O and C—H⋯Cl hydrogen bonds in the structure of (I). H atoms not involved in hydrogen bonds have been omitted for clarity. The imidazolium cation is shown in darker shading (blue in the electronic version of the paper) and its inner salt is shown in lighter shading (orange). Hydrogen bonds are shown as dashed lines. [Symmetry codes: (i) x, y − 1, z; (ii) x, −y + 1, z + ; (iii) x, y + 1, z.] |
