2-Amino-5-bromopyridinium 3-aminobenzoate

Abstract

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 R22(8) ring motif. Two inversion-related 3-aminobenzoate anions are linked through N—H...O hydrogen-bonds, forming an R22(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.
