Abstract: The title compound, C5H6N3O2+·ClO4-, is comprised of discrete perchlorate anions and 2-amino-3-nitropyridinium cations. The anion has a typical tetrahedral geometry while the cation presents a nearly planar [maximum deviation = 0.007 (8) Å] pyridinium ring. Undulating [C5H6N3O2+]n chains extending along the c-axis direction are linked via N-HO hydrogen bonds. The cations are further connected to the anions by N-HO hydrogen bonds and weak C-HO interactions, leading to the formation of a three-dimensional network.
