中文摘要：

以keggin型的磷钼酸（H3PMo12O40）、4-氨基吡啶（4-Apy）为原料,在水热条件下合成了一种新的超分子化合物（4-ApyH）3（PMo12O40）.通过元素分析、红外光谱和单晶X-射线衍射等确定了该化合物的组成和结构.单晶结构解析表明：该化合物是通过（PMo12O40）3-多酸阴离子和质子化的4-氨基吡啶阳离子（4-ApyH^＋）之间的静电引力与广泛的氢键作用形成的3维超分子结构,同时也对该化合物的电化学性质及光催化活性进行了研究.

英文摘要：

A new supramolecular compound（4-ApyH）3（PMo12O40） was synthesized by hydrothermal reaction of 4-aminopyridine（4-Apy） and H3PMo12O40.Its composition and structure were characterized by elemental analysis,infrared spectroscopy and single-crystal X-ray crystallography.The result of single-crystal X-ray diffraction analysis reveals that three-dimensional（3D） structure of the title compound was formed by electrostatic attractions,and hydrogen bonding interactions between（PMo12O40）3-and protonated 4-aminopyridine cations（4-ApyH＋）.In addition,the electrochemical property and photocatalytic activity of title compound were investigated as well.
