title: Sodium 2-nitro-cinnamate dihydrate: a one-dimensional hydrogen-bonded coordination polymer.
abstract: The title compound catena-poly[aqua-sodium-μ(2)-aqua-μ(3)-2-nitro-cinnamato], [Na(C(9)H(6)NO(4))(H(2)O)(2)](n), the sodium salt of trans-2-nitro-cinnamic acid, is a one-dimensional coordination polymer based on six-coordinate octa-hedral NaO(6) centres, comprising three facially related monodentate carboxyl-ate O-atom donors from separate ligands (all bridging) [Na-O = 2.4370 (13)-2.5046 (13) Å], and three water mol-ecules (two bridging and one monodentate) [Na-O = 2.3782 (13)-2.4404 (17) Å]. The structure is also stabilized by intra-chain water-carboxyl-ate and water-nitro O-H⋯O hydrogen bonds.
