Abstract: A coordination polymer was synthesized by solution method. Its structure was determined by single crystal X-ray diffraction analysis and further characterized by elemental, IR spectra，TG and magnetic property analysis. The title compound crystallizes in triclinic space group P-1, with a=0.476 74(12) nm，b=0.113 19(3) nm，c=0.116 14(3) nm，α=106.468(4)°，β =100.114(5)°，γ =94.358(5)°，V=0.586 4(3) nm3，Z=1. Cu(II) ions are linked by O-C-O unit to form one-dimensional chain, the 1D chains are connected by intermolecular hydrogen bonds and resulting in 2D structure. Hydrogen bonds play significant role in stabilization of the structure，weak ferromagnetic interactions are observed in the compound.
