title: catena-Poly[[[aquachloridocopper(II)]-mu-N-(6-amino-3-methyl-5-nitroso-4-oxo-3,4-dihydropyrimidin-2-yl)glycinato] monohydrate] redetermined at 120 K: a highly polarized ligand within coordination polymer chains linked by hydrogen bonds.
abstract: In the title compound, {[Cu(C(7)H(8)N(5)O(4))Cl(H(2)O)].H(2)O}(n), the bond lengths in the N-pyrimidinylglycinate unit provide evidence for a strongly polarized electronic structure. This ligand is coordinated to three Cu(II) centres, resulting in the formation of a coordination polymer in the form of a chain containing two types of centrosymmetric ring. These chains are linked by an extensive series of hydrogen bonds, including O-H...O, N-H...O, O-H...Cl and N-H...Cl types, into a continuous three-dimensional structure.
