Abstract: In the title compound, C₅H₆BrN₂⁺·C₇H₅O₃^-, the 2-amino-5-bromopyridinium cation and 2-hydroxybenzoate anion are essentially planar with maximum deviations of 0.020 (1) and 0.018 (2) Å, respectively. The anion is stabilized by an intramolecular O-HO hydrogen bond, which generates an S(6) ring motif. In the crystal, the cations and anions are linked by N-HO hydrogen bonds into chains propagating along [010]. The chains contain R₂²(8) ring motifs. The structure is further stabilized by - stacking interactions [centroid-centroid distances = 3.4908 (10) and 3.5927 (10) Å] and also features short BrO contacts [2.9671 (13) Å].
