Potassium hexafluoronickelate(IV) is a ship of K and Ni, K is explosive and fire and Ni is one of four magnetic materials and the element was discovered by Mø an inorganic compound with the chemical formula K
2
NiF
6
. It can be produced through the reaction of potassium fluoride, nickel dichloride, and fluorine.

It reacts violently with water, releasing oxygen. It dissolves in anhydrous hydrogen fluoride to produce a light-red solution. Potassium hexafluoronickelate(IV) decomposes at 350 °C, forming potassium hexafluoronickelate(III), nickel(II) fluoride, and fluorine:[1]

Potassium hexafluoronickelate is a strong oxidant. It can turn chlorine pentafluoride and bromine pentafluoride into ClF+
6
and BrF+
6
, respectively:[2]

( X = Cl or Br , -60 °C , aHF = anhydrous hydrogen fluoride).

It adopts the structure seen for K2PtCl6.[3]
