摘　　要：A novel coordination polymer [Ni（PDC）(H2O)2] was synthesized under solvothermal conditions and characterized by means of singlecrystal X-ray diffraction（XRD） analysis,elemental analysis,IR analysis,TG（analysis.） Crystal data for(C7H7NO6Ni) were obtained,（i.e.,） monoclinic(P21/c（No.14）,)（a=）（0.720 2（3）） nm,b=0.917 2（4） nm,c=0.128 79（4） nm,β=90.46（3）°,Z=4.The compound was a 2D layered coordination polymer with helical chains.In the compound,there are two helical Ni-O-C and Ni-pdc chains in one layer,and the opposite orientation of the helical chains in the adjacent layers.The layers are connected via hydrogen bonds into 3D supramolecular framework.A novel coordination polymer [ Ni（PDC） （ H2O） 2 ] was synthesized under solvothermal conditions and characterized by means of single-crystal X-ray diffraction （XRD） analysis, elemental analysis, IR analysis, TG analysis. Crystal data for C7H7NO6Ni were obtained, i.e., monoclinic P21/c（No. 14）, a= 0.720 2（3） nm, b=0.9172（4） nm, c=0.12879（4） nm, β =90. 46（3）°, Z=4. The compound was a 2D layered coordination polymer with helical chains. In the compound, there are two helical Ni-O-C and Ni-pdc chains in one layer, and the opposite orientation of the helical chains in the adjacent layers. The layers are connected via hydrogen bonds into 3D supramolecular framework.
