title: 2-Amino-5-bromo-pyridinium 2-hy-droxy-benzoate.
abstract: In the title compound, C(5)H(6)BrN(2) (+)·C(7)H(5)O(3) (-), the 2-amino-5-bromo-pyridinium cation and 2-hy-droxy-benzoate anion are essentially planar with maximum deviations of 0.020 (1) and 0.018 (2) Å, respectively. The anion is stabilized by an intra-molecular O-H⋯O hydrogen bond, which generates an S(6) ring motif. In the crystal, the cations and anions are linked by N-H⋯O hydrogen bonds into chains propagating along [010]. The chains contain R(2) (2)(8) ring motifs. The structure is further stabilized by π-π stacking inter-actions [centroid-centroid distances = 3.4908 (10) and 3.5927 (10) Å] and also features short Br⋯O contacts [2.9671 (13) Å].
