合成了一种由双核Ce单元和15元环WO 6单元组成的新型十五钨酸盐[H6 Ce 2（H2 O）Cl（W5 O 18）3]（7-）（1），并通过X射线单晶衍射对其结构进行了表征。聚阴离子1表现出蓝色光致发光，其发射最大值在488 nm处，这是铈（III）从5d到（2）F5/2态的跃迁的特征。电化学性质研究表明，化合物1具有两个可逆的氧化还原峰，属于双电子过程。
A novel pentadecatungstate, [H 6Ce 2(H 2O)Cl(W 5O 18) 3] (7-) ( 1), constructed by a dinuclear cerium unit and 15-member ring WO 6 units was prepared and characterized by single-crystal X-ray diffraction. Polyanion 1 exhibits blue photoluminescence with an emission maximum at 488 nm, which is characteristic of cerium(III) transitions from 5d to (2)F 5/2 states. Furthermore, the study of the electrochemical property investigation of 1 shows two reversible redox peaks ascribing to two-electron processes.
