Synthesis

Nickel tetrafluoride is claimed to result from the reaction of [XeF5]2[NiF6] (pentafluoroxenonium(IV) hexafluoronickelate(IV)) with AsF5 and K2[NiF6] with BF3.[3]

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 BrF5 to hexafluorobromonium(VII) cation [BrF6]+, potassium hexafluoroplatinate(V) K[PtF6] to platinum(VI) fluoride PtF6.[4]
