2-Amino-5-bromo-pyridinium 3-amino-benzoate.

In the title salt, C(5)H(6)BrN(2) (+)·C(7)H(6)NO(2) (-), the pyridine N atom of the 2-amino-5-bromo-pyridine mol-ecule is protonated. In the crystal, the protonated N atom and the 2-amino group are hydrogen-bonded to the carboxyl-ate O atoms via a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. Two inversion-related 3-amino-benzoate 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 inter-actions involving the benzene and pyridinium rings with a centroid-centroid distance of 3.7743 (15) Å.
