All the residues of the title compound, (C5H6N3O2)[ReO4]·H2O, are located on general crystallographic positions. The 2-amino-5-nitropyridinium cation has a typical planar conformation with one of the nitro O atoms −0.058 (5) Å out of plane; the amine H atoms are also a little out of the main ring plane towards the opposite side of the aforementioned O atom [by 0.02 (4) and 0.04 (4) Å]. The perrhenate anion is nearly ideally tetrahedral. Three distinct N—H...O hydrogen bonds give rise to C(8) zigzag chains running along [100]. R44(12) rings involving the two hydrogen bonds in which the water molecules interact with the perrhenate anions are also present.
