In the title compound, {(NH4)[Ag(C5HN2O6)2(H2O)]}n, the AgI cation is seven-coordinated and is surrounded by four oxo O atoms of the 2,3,5,6-tetraoxo-4-nitropyridin-4-ide species [Ag-O = 2.3848 (19), 2.4931 (18), 2.5361 (18) and 2.573 (2) Å], two nitro O atoms [Ag-O = 2.644 (2) and 2.661 (2) Å], and one water molecule [Ag-O = 2.3133 (19) Å]. The pyridin-4-ide mono-anions act as polydentate bridging ligands and form a three-dimensional network that is stabilized through O-H...O and N-H...O hydrogen bonds involving the coordinating water molecule and the imide function as donator groups. The ammonium cations are located in the cavities of the framework and are also involved in hydrogen bonding to O atoms of the ligand.
