摘要:

以磷钼酸、 2-氨基吡啶、 五氧化二钒、 氯化锌和氯化镍等为主要原料, 采用水热方法合成了2个簇基超分子化合物[H3PMo12O40]2[C5H6N2]6(1)和[H2PMo12V2O42][C5H6N2]5·3H2O(2)(C5H6N2=2-氨基吡啶). 通过元素分析、 红外光谱、 紫外-可见光谱、 X射线光电子能谱、 热重分析、 X射线单晶衍射及X射线粉末衍射等手段对化合物进行了结构表征. 结构分析显示, 簇单元不同的2个超分子化合物以各自独特的堆积方式形成三维超分子网络. 利用苯乙烯的环氧化反应研究了2个化合物的催化性能.

Abstract:

Two new supramolecular complexes, [H3PMo12O40]2[C5H6N2]6(1) and [H2PMo12V2O42]·[C5H6N2]5·3H2O(2)(C5H6N2=2-pyridylamine), were synthesized and characterized by means of elemental analysis, infrared spectroscopy(FTIR), UV-Vis spectrum(UV-Vis), X-ray photoelectron spectroscopy(XPS), thermal gravimetric(TG) analysis, power X-ray diffraction(PXRD) and single-crystal X-ray diffraction analysis. Both of compounds 1 and 2 consisting of different clusters were assembled into 3D inorganic supramoleculae network with different packing modes. In addition, the catalytic properties of two complexes were investigated using the epoxidation of styrene.

Key words: Polyoxomatelate, Supramolecular compound, 2-Pyridylamine, Hydrothermal synthesis, Catalytic property
