In the title compound, C5H6BrN2
−, the pyridine N atom of the 2-amino-5-bromopyridine molecule is protonated. The
protonated N atom and the amino group are linked via N—H⋯O hydrogen bonds to the carboxylate O atoms of the singly deprotonated succinate
anion. The hydrogen succinate anions are linked via O—H⋯O hydrogen bonds. A weak intermolecular C—H⋯O hydrogen bond is also observed.
