Hydrothermal Synthesis and Crystal Structure of Keggin-type (C_(12)H_9N_2)_3[PMo_(12)O_(40)] Complex

采用水热反应合成了有机-无机杂化的Keggin型配合物(C12H9N2)3[PMo12O40],并通过X-射线单晶衍射对其结构进行了分析。该配合物为正交晶系P212121空间群,晶胞参数为a=1.20800(1)nm,b=2.10108(4)nm,c=2.24234(5)nm。配合物包含了孤立的Keggin型[PMo12 O40]阴离子和3个质子化的1,10-菲咯啉。在Keggin型阴离子和质子化的1,10-菲咯啉之间存在C—H…O作用,而在1,10-菲咯啉之间存在π…π作用,分子间通过这2种弱的作用形成三维超分子结构。

The organic-inorganic hybrid Keggin-type complex（C12H9N2）3 had been synthesized under hydrothermal condition,and the structure of the complex was characterized by single-crystal X-ray diffraction.The complex crystallizes in orthorhombic,space group P212121 with a=1.20800（1）nm,b=2.10108（4）nm,c=2.24234（5）nm.The structure of the complex contains one isolated anion and three protonated 1,10-phenanthroline molecules.The C—H…O interactions exist between the Keggin anion and the protonated 1,10-phenanthroline molecule,and the π…π weak interaction exists between the 1,10-phenanthroline molecules.The overall structure displays a three-dimensional supramolecular framework.
