A mixed-valence uranium(IV,VI) germanate has been synthesized under high-temperature, high-pressure hydrothermal conditions. The structure contains discrete U(IV)O(6) octahedra and U(VI)O(6) tetragonal bipyramids, which are connected by three-membered single-ring Ge(3)O(9)(6-) anions to form a three-dimensional framework with 9-ring channels. The U 4f X-ray photoelectron spectroscopy spectrum was measured to identify the valence states of the uranium.
在高温高压水热条件下合成了一种混合价铀(IV,VI)锗酸盐。该结构包含离散的 U(IV)O(6)八面体和 U(VI)O(6)四方双锥，它们通过三个成员的单环 Ge(3)O(9)(6-)阴离子连接，形成具有 9 元环通道的三维框架。通过测量 U 4f X 射线光电子能谱来确定铀的价态。
