POTASSIUM HEXAFLUORONICKELATE(IV) Chemical Properties,Usage,Production

Reaction

A source of F2; decomposes on heating, evolving F2 (400°C)

Chemical Properties

dark pink to pink purple crystalline powder or

Chemical Properties

Potassium hexafluoronickelate(IV) evolves oxygen from water but gives bright red solutions in anhydrous hydrogen fluoride. Above 350° in vacuo it decomposes according to: 3K2NiF6 → 2K3NiF6+NiF2+F2
