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[H 3PMo 12 O 40]2[C 5H 6N 2]6(1)和[H 2PMo 12 V 2O 42][C 5H 6N 2]5·3H 2O(2)(C 5H 6N 2=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.
Two new supramolecular complexes,[H 3PMo 12 O 40]2[C 5H 6N 2]6(1)and[H 2PMo 12 V 2O 42]·[C 5H 6N 2]5·3H 2O(2)(C 5H 6N 2=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.
