[(CH3)2NH]3[H3PMo12O40]的合成、结构及表征

Synthesis,Structure and Characterization of [(CH_3)_2NH]_3[H_3PMo_(12)O_(40)]

通过水热合成法,成功合成了化合物[(CH_3)_2NH]_3[H_3PMo_(12)O_(40)],并通过单晶X射线衍射,IR,XRD,元素分析和电化学分析对该化合物进行表征。该化合物中,Keggin型磷钼酸之间通过氢键形成二维折叠层,这些层按照ABCD沿c轴方向堆积。二甲胺分子分布在层间,通过氢键连接相邻的来自不同层的两个Keggin型磷钼酸,将二维折叠层进一步拓展成三维超分子骨架。

A new compound,[（CH_3）_2NH]_3[H_3PMo_（12）O_（40）] was synthesized by hydrothernal method.The structure was determined by single crystal X-ray diffraction,IR,XRD,elemental analyses and electrochemical analyses.In this compound,the Keggin-POMs units were linked each other to form a two-dimensional folded layer by hydrogen bonds,such layers arrayed along c-axis by ABCD mode.The dimethylamine molecules reside in the interlayer,and further linked two nearly Keggin-POMs from different layers,to form 3D supramolecular structure from the 2D folded layer.
