title: A one-dimensional zigzag coordination polymer: catena-poly[[diaquapyridinenickel(II)]-mu-pyridine-2,3-dicarboxylato-kappa3N,O2:O3].
abstract: The asymmetric unit of the title one-dimensional coordination polymer, [Ni(C(7)H(3)NO(4))(C(5)H(5)N)(H(2)O)(2)](n), contains a quinolinate dianion, a nickel(II) ion, two water molecules and a pyridine molecule. The pyridine-2,3-dicarboxylate (quinolinate) ligands connect the nickel(II) ions in a head-to-tail fashion, resulting in the formation of a one-dimensional zigzag chain. Adjacent chains form pairs via an extensive network of hydrogen-bonding interactions. A weak C--H...O intermolecular hydrogen bond links neighboring pairs of chains, thus generating two-dimensional double-sheet layers that are stabilized via pi-pi-stacking interactions between adjacent quinolinate pyridyl rings.
