Nickel tetrafluoride

Nickel tetrafluoride is an inorganic compound with a chemical formula NiF4.

Synthesis
Nickel tetrafluoride is claimed to result from the reaction of (XeF5)2NiF6 with AsF5 and K2NiF6 with BF3.

Chemical properties
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.
