Characteristic

 

Potassium hexafluoronickelate(IV) is an inorganic compound with the chemical formula K₂NiF₆. 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.
