catena-poly[[[{N-(6-amino-3,4-dihydro-3-methyl-5-nitroso-4-oxopyrimidin-2-yl)glycinato-O}penta-aquastrontium]-mu-N-(6-amino-3,4-dihydro-3-methyl-5-nitroso-4-oxopyrimidin-2-yl)glycinato-O : O '] monohydrate]: coordination polymer chains linked by hydrogen bonds into a three-dimensional framework

In the title compound, [Sr(C7H8N5O4)(2)(H2O)(5)].H2O, one of the anionic (C7H8N5O4)(-) ligands acts as a simple monodentate ligand coordinated via a carboxyl O atom, while the other acts as a bridging ligand between pairs of Sr atoms, utilizing one carboxyl O and the nitroso O atom, so generating a one-dimensional coordination polymer. Five water molecules are coordinated to Sr, resulting in eight-coordination in the form of a distorted square antiprism, while the sixth water molecule is hydrogen bonded to a coordinated water. The coordination polymer chains are reinforced by O-H...N and O-H...O hydrogen bonds and are linked into a three-dimensional framework by an extensive series of N-H...O and O-H...O hydrogen bonds.
