摘要
以ZnF2和吡啶-2,4-二甲酸为原料,运用水热法在120oC下反应两天,合成了一个配合物超分子[Zn(pydc)(Hpydc)(H2O)2]·Him·H2O(1,H2pydc=吡啶-2,4-二甲酸,im=咪唑).并对配合物进行了X射线单晶衍射、X射线粉末衍射、红外光谱、热稳定性分析以及室温固态荧光光谱等表征.结果表明:配合物属于三斜晶系,P-1空间群,晶胞参数a=7.3791(6),b=10.6071(8),c=13.2907(10),α=81.3620(10)°,β=77.4610(10)°,γ=79.5930(10)°;V=992.06(13)3,Z=2.室温固态荧光结果显示,配合物呈现蓝色荧光.
A new supramolecular complex [Zn(pydc) (Hpydc) ( H2O)2 ]· Him · H2 O ( 1 ) was synthesized byhydrothermal method. The reaction was performed at 120℃ for two days, taking ZnF2 and pyridine-2,4-dicarboxylic acid as raw materials. The complex was characterized by X-ray single crystal diffraction, X-ray powder diffraction, infrared spectrum, thermal stability analysis and solid state fluorescence analysis at room temperature. The results show that the complex crystallizes in triclinic, space group P 1 with cell parameters : a = 7. 3791 (6) A, b = 10. 6071 (8) A, c = 13. 2907 (10) A, a = 81. 3620(10)°, β=77.4610(10)°, y=79.5930(10)°; V=992.06(13) A3,Z=2. Solid state fluorescence at room temperature indicates that the complex exhibits blue fluores- cence.
