Abstract
ALTHOUGH potassium heptafluoroprotactinate (V), K2PaF7, has been known for several years1 and a number of hexafluoroprotactinates (V), MIPaF6, (MI = NH4+, K+ and Rb+) have been recently reported2, Octafluoroprotactinates (V) have not been recorded. In an investigation of the preparation and properties of the fluorocomplexes of quinquevalent protactinium, using bromine trifluoride and aqueous hydrofluoric acid as solvents, we have isolated lithium and sodium octafluoroprotactinates (V), Li3PaF8 and Na3PaF8 respectively, from reactions in the latter solvent.
