title: 1,3-Diallyl-2-methyl-benzimidazolium bromide dihydrate.
abstract: The bonds in the five-membered ring of the title hydrated salt, C(14)H(17)N(2) (+)·Br(-)·2H(2)O, are delocalized. The cation lies on a special position of m site symmetry such that the mirror plane passes through the imidazol-yl-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 mol-ecule are linked into a chain by O-H⋯O hydrogen bonds. One of the water O atoms is disordered over two sites of equal occupancy.
