Preparation And Characterization Of The Uranyl Fluoride Antimony Pentafluoride Adduct, Uf2o2.4sbf5

When UF4O·2SbF5 is treated with anhydrous hydrogen fluoride a slow reaction in solution takes place. Investigation of this reaction and those of UF4O–SbF5–HF solutions on standing have shown that, in both cases, UF6 and a new uranyl fluoride derivative, UF2O2·4SbF5 are produced.
