title: [N-(6-amino-3,4-dihydro-3-methyl-5-nitroso-4-oxopyrimidin-2-yl)-glycylglycinato]aquapotassium, a three-dimensional coordination polymer.
abstract: In the title compound, polymeric potassium N-(6-amino-3,4-dihydro-3-methyl-5-nitroso-4-oxopyrimidin-2-yl)glycylglycinate hydrate, (K(+).C(9)H(11)N(6)O(5)(-).H(2)O)(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) A. 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 K(2)O(2) rings. The structure is analysed in terms of (010) metal-ligand sheets linked by [010] chains of fused rings.
