| 摘 要： | 无机-有机杂化多酸化合物具有优良的物理、化学性质，对其开展深入研究具有重要的意义。通过水热合成方法合成了化合物[H2pca][H3SiW12O40]·2H2O(1) (pca=吡啶-4-甲酸)，并对其结构和性质进行研究。经X线单晶衍射仪检测并分析发现，该化合物属于单斜晶系、C2/m空间群，通过配体与多酸之间的氢键形成三维的超分子结构。通过红外光谱、X线粉末衍射、荧光光谱、热重分析对其性质进行表征，在进行荧光光谱分析时发现，该化合物在λ=410 nm处存在荧光吸收峰，并具有较好的热稳定性。该研究可丰富无机-有机杂化多酸化合物的家族，为进一步应用研究打下基础。

| Abstract: | Polyoxometalate (POM)-supported inorganic-organic hybrid compounds have attracted extensive attention for its superior physical and chemical properties. It is important to research. [H2pca][H3SiW12O40]·2H2O(1) (pca = Pyridine-4-carboxylic acid), which has been obtained by hydrothermal methods and characterized by single-crystal X-ray diffraction analyses, IR spectra, powder X-ray diffraction, and thermal analyses. It belongs to monoclinic crystal system and C2/m space group. Hydrogen bonds of ligand and [SiW12O40]4- lead to a three-dimensional supramolecular structure. In addition, fluorescence spectra was also investigated. The experimental results show that the compound has a fluorescence absorption peak at λ = 410 nm, and also has good thermal stability. This work extends POM-supported inorganic-organic hybrid compounds, and it will be a strong foundation for further application. |
