2,3-Diamino-pyridinium 3-amino-benzoate.

ABSTRACT: In the title salt, C(5)H(8)N(3) (+)·C(7)H(6)NO(2) (-), the pyridine N atom of the 2,3-diamino-pyridine mol-ecule is protonated. The proton-ated N atom and one of the two N atoms of the 2-amino groups are hydrogen bonded to the 3-amino-benzoate anion through a pair of N-H?O hydrogen bonds, forming an R(2) (2)(8) ring motif. The carboxyl-ate mean plane of the 3-amino-benzoate anion is twisted by 8.81?(7)° from the attached ring. The crystal structure is further stabilized by ?-? inter-actions [centroid-centroid distance 3.6827?(7)?Å].
