2-Amino-5-nitropyridinium hydrogen oxalate

In the cation of the title molecular salt, C5H6N3O2+·C2HO4−, the dihedral angle between the aromatic ring and the nitro group is 3.5 (3)°; in the anion, the dihedral angle between the CO2 and CO2H planes is 10.5 (2)°. In the crystal, the anions are linked into [100] chains by O—H...O hydrogen bonds....
