A new supramolecular complex[Zn(pydc)(Hpydc)(H_2O)_2]·Him·H_2O(1)was synthesized by hydrothermal method.The reaction was performed at 120 ℃ for two days,taking ZnF_2 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.
