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

Balasubramani K, Fun HK - Acta Crystallogr Sect E Struct Rep Online (2009)

Bottom Line: 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 π-π inter-actions [centroid-centroid distance 3.6827 (7) Å].

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 π-π inter-actions [centroid-centroid distance 3.6827 (7) Å].
