Pentahalogeno-oxouranates(VI)

Abstract
Pentafluoro- and tetrabromochloro-oxouranate(VI) salts, [Ph4P][UOF5] ana [Ph4P][UOClBr4], have been prepared by reaction of [Ph4P][UOCl5] with hydrogen fluoride and bromide respectively. Hydrolysis of [Ph4P]-[UOCl5] leads to a uranium(VI) anion which may contain a cis-dioxouranium(VI) group. The electron-transfer and vibrational spectra of these salts are discussed and compared with those of the corresponding tungsten(VI) species. A simple method for the preparation of [Ph4P][WOF5] is also reported.
