1-(6-Bromo­pyridin-2-yl)-3-methyl-3H-imidazol-1-ium bromide monohydrate

The structure of the title compound, C₉H₉BrN₃⁺·Br^-·H₂O, was determined at 150 K. It is a supramolecular adduct of imidazolium bromide and water mol­ecules. Helical chains of (H₂O·Br^-) exist in the structure along the [001] direction. Each chain forms extensive hydrogen bonds with the imidazolium cations.
