摘要
A 1-D paddle-wheel copper (II) coordination polymer constructed by 2-nitrobenzene-1,4-di(oxyacetic) acid has been synthesized by hydrothermal reaction, and its crystal structure was determined by X-ray diffraction. The crystal is of triclinic, space group P1̄ with a = 7.7257(12), b = 8.3648(13), c = 11.5516(18) Å, a = 76.654(2), β = 82.088(2), γ = 63.636(2)°, C20H22Cu2N 2O20, Mr = 737.48, V = 650.27(18) Å3, Dc = 1.883 g/cm3, F(000) = 374, μ = 1.737 cm-1 and Z = 1. The final refinement gave R = 0.0345 and wR = 0.0995 for 1996 observed reflections with I > 2σ(I). The coordination polymer demonstrates a 1-D microporous structure, and the channel is formed by two NBDOA2- and two Cu2+ ions. The ligand NBDOAH 2 displays a good flexible characteristic. The 1-D chains are connected to a 3-D supramolecular network by hydrogen bonds.
