2-Amino-5-bromopyridinium 3-aminobenzoate

In the title salt, C5H6BrN2 +·C7H6NO2 −, the pyridine N atom of the 2-amino-5-bromopyridine molecule is protonated. In the crystal, the protonated N atom and the 2-amino group are hydrogen-bonded to the carboxylate O atoms via a pair of N—H⋯O hydrogen bonds, forming an R 2 2(8) ring motif. Two inversion-related 3-aminobenzoate anions are linked through N—H⋯O hydrogen-bonds, forming an R 2 2(14) ring motif. The crystal structure is further stabilized by π⋯π interactions involving the benzene and pyridinium rings with a centroid–centroid distance of 3.7743 (15) Å.
