catena-Poly[[[N-(4-amino-1,6-dihydro-1-methyl-5-nitroso-6-oxopyrimidin-2-yl)-(S)-glutamato]hexaaqua-barium]-mu-N-(4-amino-1,6-dihydro-1-methyl-5-nitroso-6-oxopyrimidin-2-yl)-(S)-glutamato]: coordination polymer chains linked into a three-dimensional framework by N-H center dot center dot O and O-H center dot center dot center dot O hydrogen bonds

In the title complex, [Ba(C10H12N5O6)(2)(H2O)(6)](n) the Ba atom is nine-coordinated by six water ligands and three carboxylate O atoms. The Ba2+ cations and the anionic glutamate ligands form coordination polymer chains, and these chains are linked by pairs of N-H••• O hydrogen bonds and pairs of O-H••• O hydrogen bonds to form a continuous three-dimensional framework of cations and anions, which is reinforced by hydrogen bonds involving the water molecules.
