Nickel tetrafluoride is a binary inorganic compound of nickel and fluorine with a chemical formula of NiF4.[1][2]
Nickel tetrafluoride can be obtained from the reaction of (XeF5)2NiF6 with AsF5 and K2NiF6 with BF3.[3][4]
Nickel tetrafluoride forms a tan-colored solid. It is unstable to F2 loss above –65°C to create NiF3.[3]
Nickel tetrafluoride is an extremely strong oxidizer. The oxidizing properties are enhanced in presence of Lewis acids in anhydrous HF. In terms of oxidizing power, it is comparable to krypton difluoride. It can oxidize bromine pentafluoride to hexafluorobrome(VII) cation, potassium hexafluoroplatinate(V) to platinum(VI) fluoride.[5]
The compound is used in inorganic synthesis as a substitute for unstable krypton difluoride, since it is quite easily synthesized from available and stable potassium hexafluoronickelate(IV).
