Synthesis, Structure, and Properties of Cesium Polyuranate [Cs2(H2O)3][(UO2)6O3(OH)8]·2H2O

Cesium uranate [Cs 2 (Н 2 О) 3 ][(UO 2 ) 6 O 3 (OH) 8 ]·2H 2 O was obtained by reacting hydrated uranium(VI) oxide UO 3 ·2.25H 2 O with a cesium nitrate aqueous solution under hydrothermal conditions at 100°C within two weeks. Composition and structure of the resulting compound was determined by the...

Zusammenfassung:Cesium uranate [Cs 2 (Н 2 О) 3 ][(UO 2 ) 6 O 3 (OH) 8 ]·2H 2 O was obtained by reacting hydrated uranium(VI) oxide UO 3 ·2.25H 2 O with a cesium nitrate aqueous solution under hydrothermal conditions at 100°C within two weeks. Composition and structure of the resulting compound was determined by the chemical analysis, IR spectroscopy, X-ray diffraction, and differential thermal analysis. Its dehydration and thermal decomposition were studied.
