摘　　要：利用混合溶剂热合成方法,获得了一维柱状铜配位聚合物:[Cu(L)2(3,4-HTDC)2](L为N,N′-双(3-吡啶基)-1,3-双甲酰胺;3,4-H2TDC为3,4-噻吩二羧酸).配位聚合物的单晶结构为三斜晶系,P-1空间群,a=8.1069(6)A,b=12.0333(9)A,c=13.0796(10)A,α=114.1270(10)°,β=92.669(2)°,γ=107.528(2)°,Z=2,V=1089.11(14)A3(CCDC号:1940520).粉末-X射线衍射、元素分析和热重分析表明,配合物具有较好的体相纯度和热稳定性.此外,配合物的电化学性质研究表明,其对BrO-3和NO-2具有较好的电催化还原性质.A one-dimensional columnar copper coordination polymer was obtained by mixed-solvothermal synthesis:[Cu(L)2(3,4-HTDC)2](L=N,N′-bis(3-pyridine)-1,3-diformamide,3,4-H2TDC=3,4-thiophene dicarboxylic acid).The crystal structure is in triclinic crystal system,space group P-1,a=8.1069(6)A,b=12.0333(9)A,c=13.0796(10)A,α=114.1270(10)°,β=92.669(2)°,γ=107.528(2)°,Z=2,V=1089.11(14)A3(CCDC:1940520).The X-ray powder diffraction,elemental analysis and thermogravimetry show that the title complex has good phase purity and thermal stability.In addition,the title complex has good electrocatalytic properties for the reduction of BrO-3 and NO-2.
