摘要： 本文报道由H2PDC合成的新型维层状无机-有机骨架晶体Ni(PDC)(H2O)2(H2PDC=吡啶-2,5-二羧酸), 该化合物的一层是由右手螺旋Ni—O—C链与左手螺旋Ni-pdc链组成, 而邻近的一层则是由左手螺旋Ni—O—C链与右手螺旋Ni-pdc链组成, 层与层之间通过氢键作用形成了三维超分子结构. 用ICP、TG、IR和X射线单晶衍射分析等手段对其结构进行表征.

Abstract: 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=0.917 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.

Key words: Inorganic-organic framework material, Pyridinecarboxylate, Helical chains
