Synthesis,Structure and Properties of A Hybrid Material Based on Polyoxoanion and Copper Phosphate

本文采用水热法合成了一个新的金属有机-无机杂化化合物[Cu4(phen)4(HPO4)2(H2O)2(OH)2][HPMo12O40]·H2O(1)(phen=邻菲咯啉)。通过元素分析、红外光谱、热重分析、X-射线单晶衍射对其进行了结构表征。化合物1是由四核铜磷酸盐、Keggin阴离子和晶格水分子组成。四核铜磷酸盐和多阴离子之间通过弱的M…O相互作用形成二维结构(M=Cu,Mo),该二维结构通过氢键和π-π相互作用形成三维超分子框架,还对化合物1的电化学和电催化性质进行了研究。

A new metalorganic-inorganic hybrid compound [Cu4（phen）4（HPO4）2（H2O）2（OH）2][HPMo12O40]·H2O （1） （phen=1,10-phenanthroline）, has been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectrum, thermal analysis and single-crystal X-ray structural analysis. Compound 1 is consisted of a tetranuclear copper phosphate [Cun（phen）4（HPO4）2（H2O）2（OH）2]^2＋, Keggin polyoxoanion [HPMo12O40]〉 and the lattice water molecule. Compound 1 generates an interesting 2D network between the tetranuclear copper phosphates and polyoxoanions by weak M…O interactions （M=Cu, Mo）, which is further connected into a 3D supramolecular architecture through hydrogen bonds and π-π interactions. Compound 1 was used as a solid bulk modifier to fabricate a carbon paste electrode （1-CPE） by direct mixing. The electrochemical and electrocatalytic behaviors of the 1-CPE have been studied in detail. CCDC： 666620.
