2,3-Diaminopyridinium benzoate
Abstract
In the title compound, C5H8N3+·C7H5O2−, the pyridine N atom is protonated. The carboxylate group of the benzoate anion is twisted away from the attached ring by 10.91 (9)°. In the crystal structure, N—H...O hydrogen bonds between 2,3-diaminopyridinium cations and benzoate anions, and π–π interactions between the pyridinium rings [centroid–centroid distance = 3.6467 (9) Å] form a two-dimensional network parallel to (001). In the network, N—H...O hydrogen bonds form R22(8) and R21(7) ring motifs.
