| 摘要: 以硝酸镉、环已二酸(H2CDC)和2，3，5，6-四氟-1，4-二咪唑基二甲苯(FBIX)为原料，在水热条件下得到了1个配位聚合物[Cd(CDC)(FBIX)0.5]n(1)，并利用元素分析、红外光谱以及X-射线单晶洐射对其进行了表征。该晶体属三斜晶系，P1 空间群，a=0.880 53(18) nm,b=0.888 31(18) nm，c=1.091 7(2) nm，α=97.349(2)°，β=95.688(2)°，γ=105.495(2)°，V=0.808 1(3) nm3，Dc=1.799 g·cm-3,Z=2，F(000)=434，Goof=1.094，R1=0.025 6，wR2=0.072 3。Cd(Ⅱ)离子通过2个CDC配体桥联形成一维双绞链，再通过FBIX配体连接成二维层状结构。室温下该配合物表现出较强的荧光发射。 | |

| Abstract: A two-dimensional coordination polymer of [Cd(CDC)(FBIX)0.5]n(1) (H2CDC=1,4-cyclohexanedicarbo-xylic acid and FBIX=2,3,5,6-tetrafluoro-1,4-bis(imidazol-1-yl-methyl) benzene) has been prepared and characterized by elemental analysis, IR spectroscopy, TGA and single-crystal X-ray diffraction. The crystal is of triclinic system, space group P1 with a=0.880 53(18) nm, b=0.888 31(18) nm, c=1.091 7(2) nm, α=97.349(2)°, β=95.688(2)°, γ=105.495(2)°, V=0.808 1(3) nm3, Dc=1.799 g·cm-3, Z=2, F(000)=434, Goof=1.094, R1=0.025 6, wR2=0.072 3. Complex 1 shows a two-dimensional layer structure based on paddle-wheel building units. Moreover, it shows intense fluorescent property at room temperature. CCDC: 785745. | |
