Abstract: The bonds in the five-membered ring of the title hydrated salt, C₁₄H₁₇N₂⁺·Br^-·2H₂O, are delocalized. The cation lies on a special position of m site symmetry such that the mirror plane passes through the imidazolyl-methyl bond and is perpendicular to the plane of the cation. The anion lies on another special position of 2 site symmetry. The anion and uncoordinated water molecule are linked into a chain by O-HO hydrogen bonds. One of the water O atoms is disordered over two sites of equal occupancy.
