文摘

The first mixed-valence uranium(IV,V) silicate is synthesized under high-temperature, high-pressure hydrothermal conditions. The structure contains chains of corner-sharing U^IV,VO₆ octahedra which are interconnected by Si₄O₁₂ four-membered rings to form a 3-D framework. XPS and XANES spectra were measured to identify the valence state of uranium.
