ABSTRACT: We present the syntheses of the hexafluoridouranates(V) MUF₆ (M = Li-Cs, Ag, Tl, H₃O) and of the dodecafluoridodiuranate(V) Ba[U₂F₁₂]·1.36HF. With the exception of AgUF₆ and H₃OUF₆, all compounds were synthesized by reacting the respective metal fluorides with β-UF₅ in anhydrous hydrogen fluoride (aHF). AgUF₆ was obtained as a side product in the oxidation of Ag powder with UF₆ under a CO atmosphere, while H₃OUF₆ was obtained from the controlled hydrolysis of β-UF₅ with SiO₂ in aHF. For this hydrolysis, silica glass wool proved to be the superior choice of SiO₂. X-ray diffraction experiments on single crystals of
