2-Amino-3-ammonio­pyridinium dichloride

The asymmetric unit of the title compound, C(5)H(9)N(3) (2+)·2Cl(−), contains two diprotonated 2,3-diamino­pyridine cations and four chloride anions. In the crystal structure, the anions and cations are connected by inter­molecular N—H⋯Cl and C—H⋯Cl hydrogen bonds, forming a three-dimensional network. The crystal structure is further stabilized by π–π inter­actions between pyridinium rings [centroid–centroid distance = 3.695 (1) Å].
