A 1-D paddle-wheel copper (II) coordination polymer constructed by 2-nitro-benzene-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 P1 with a=7.7257(12),b=8.3648(13),c=11.5516(18),α=76.654(2),β=82.088(2),γ=63.636(2)o,C20H22Cu2N2O20,Mr=737.48,V=650.27(18)3,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 NBDOAH2 displays a good flexible characteristic. The 1-D chains are connected to a 3-D supramolecular network by hydrogen bonds.
