Terbium(IV) fluoride
Terbium(IV) fluoride is an inorganic compound with a chemical formula TbF4. It is a white solid that is a strong oxidizer. It can be produced by the reaction between very pure terbium(III) fluoride and xenon difluoride, chlorine trifluoride or fluorine gas:[1]
- 2 TbF3 + F2 → 2 TbF4

Properties
Terbium(IV) fluoride hydrolyzes quickly in hot water, producing terbium(III) fluoride and terbium oxyfluoride (TbOF). Heating terbium(IV) fluoride will cause it to decompose into terbium(III) fluoride and fluorine gas.[2]
- 2 TbF4 → 2 TbF3 + F2↑
The reaction will produce the mixed valence compound Tb(TbF5)3, which has the same crystal form as Ln(HfF5)3.[3]
Terbium(IV) fluoride can oxidize cobalt trifluoride into cobalt tetrafluoride:[4]
- TbF4 + CoF3 → TbF3 + CoF4↑
It can fluoronate [60]fullerene at 320–460 °C.[5]
When terbium(IV) fluoride reacts with potassium chloride and fluorine, it can produce the mixed valence compound KTb3F12.[6] A mixture of rubidium fluoride, aluminium fluoride and terbium(IV) fluoride produces Rb2AlTb3F16.[7]
