We report on the first example of a peroxouranium-containing {P8W48} wheel, [{(UO2)4(O2)4}2(P8W48O184)]40– (1), which was synthesized by a one-pot reaction of UO2(NO3)2·6H2O with the 48-tungsto-8-phosphate wheel [H7P8W48O184]33− and aqueous hydrogen peroxide in a pH 6 lithium acetate solution at 50 °C. Polyanion 1 comprises two tetrauranyl squares with side-on peroxo bridging ligands in the cavity of the {P8W48} wheel, and was isolated as the hydrated potassium–lithium salt K18Li22[{(UO2)4(O2)4}2(P8W48O184)]·133H2O (KLi-1), which was characterized in the solid state by single-crystal X-ray diffraction, as well as thermogravimetric and elemental analyses. A detailed Fourier transform infrared and Raman spectroscopy study was also performed.

含过氧呋喃基W 48轮：合成，结构以及详细的红外和拉曼光谱研究
我们报告了第一个含过氧铀的{P 8 W 48 }车轮[[（（UO 2）4（O 2）4 } 2（P 8 W 48 O 184）] 40–（1）的例子，通过一锅反应UO 2（NO 3）2 ·6H 2 O与48-钨-8-磷酸盐轮[H 7 P 8 W 48 O 184 ] 33−合成在50°C的pH 6醋酸锂溶液中加入过氧化氢水溶液。聚阴离子1包含两个在{P 8 W 48 }轮腔中带有侧向过氧桥接配体的四铀烷基，并被分离为水合钾锂盐K 18 Li 22 [{（UO 2）4（O 2）4 } 2（P 8 W 48 O 184）]·133H 2 O（KLi-1），通过单晶X射线衍射以及热重分析和元素分析表征为固态。还进行了详细的傅立叶变换红外和拉曼光谱研究。
