The fluoronickelates are a class of chemical compounds containing an anion with nickel at its core, surrounded by fluoride ions which act as ligands. This makes it a fluoroanion . The nickel atom can be in a range of oxidation states from +2, +3 to +4.
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.
