title: 4-Amino-3-ammonio-pyridinium dinitrate.
abstract: In the crystal structure of the title compound, C(5)H(9)N(3) (2+)·2NO(3) (-), the cations and anions are connected by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional network. The crystal structure is further stabilized by π⋯π inter-actions between pyridinium rings [centroid-centroid distance = 3.775 (4) Å].
