2,3-Diaminopyridinium 3-aminobenzoate

In the title salt, C5H8N3 +·C7H6NO2 −, the pyridine N atom of the 2,3-diaminopyridine molecule is protonated. The protonated N atom and one of the two N atoms of the 2-amino groups are hydrogen bonded to the 3-aminobenzoate anion through a pair of N—H⋯O hydrogen bonds, forming an R 2 2(8) ring motif. The carboxylate mean plane of the 3-aminobenzoate anion is twisted by 8.81 (7)° from the attached ring. The crystal structure is further stabilized by π–π interactions [centroid–centroid distance 3.6827 (7) Å].
