Abstract: In the title compound, C₅H₅Br₂N₂⁺·Br^-·0.5H₂O, 3-amino-2,6-dibromopyridine is protonated on the amine N atom and this cation is planar, excluding the H atoms attached to N. The organic cation, bromide anion and interstitial water molecule are held together by hydrogen bonding, bromine-bromine interactions and by a special type of electrostatic interaction between aryl bromine and the centroids of two pyridine rings, forming a bridge-like non-covalent bond.
