Protactinium(V) fluorideis a fluoride of protactinium, with the chemical formula PaF5.


Protactinium(V) fluoride can be obtained by reacting protactinium(V) oxide with bromine trifluoride or bromine pentafluoride at 600 °C:[1]

It can also be obtained by reacting protactinium(V) chloride or protactinium(IV) fluoride with fluorine gas at 700 °C:[1]

The hydrate form of protactinium(V) fluoride can be formed by the reaction of protactinium(V) oxide and hydrofluoric acid in an aqueous solution:[1]

It can also be decomposed from fluorine-containing protactinium complexes.[2]
