Abstract：A new supramolecular complex [Zn(pydc)(Hpydc)(H2O)2]·Him·H2O (1) was synthesized by hydrothermal method. The reaction was performed at 120oC 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) ?， 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. Solid state fluorescence at room temperature indicates that the complex exhibits blue fluorescence.
