In the title compound, polymeric potassium N-(6-amino-3,4-dihydro-3-methyl-5-nitroso-4-oxopyrimidin-2-yl)glycylglycinate hydrate, (K+·C9H11N6O5−·H2O)n, the hexacoordinate K+ cation is linked to five different anions as well as to the water molecule, with K—O distances in the range 2.617 (2)–2.850 (2) Å. Four of the O atoms in each anion coordinate to K centres, one of them acting as a bridging ligand, leading to the formation of nearly square centrosymmetric K2O2 rings. The structure is analysed in terms of (010) metal–ligand sheets linked by [010] chains of fused rings.
