title: Bis[N-(6-amino-3,4-dihydro-3-methyl-5-nitroso-4-oxypyrimidin-2-yl)glycyl-glycinato]triaquacalcium: coordination polymer chains linked by hydrogen bonds.
abstract: In the title compound, [Ca(C9H11N6O5)2(H2O)3], the Ca atom lies on a twofold rotation axis in C2/c and the three water molecules are all disordered, each over two sites having equal occupancy. The anion acts as a bridging ligand between pairs of Ca sites on the same twofold axis, thus forming a one-dimensional coordination polymer, with the chains lying along the twofold axes. These chains are linked by multiple O-H...O and N-H...O hydrogen bonds into a single three-dimensional framework.
