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髤离子通过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。
A coordination polymerization was obtained under hydrothermal conditions using cadmium nitrate, cyclohexanedioic acid (H2CDC) and 2,3,5,6-tetrafluoro-1,4-diimidazolylxylene (FBIX) as raw materials [Cd (CDC) (FBIX) 0.5] n (1) was synthesized and characterized by elemental analysis, IR and X-ray single shot. The crystal belongs to the triclinic system, 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, , wR2 = 0.072 3. Cd 髤 ions are bridged by two CDC ligands to form one-dimensional double-hinge chains, which are then connected into two-dimensional layered structures by FBIX ligands. The complex shows strong fluorescence emission at room temperature.
