Lithium hexafluorotungstate is an inorganic chemical compound with the chemical formula LiWF6.[1][2]

Synthesis

Lithium hexafluorotungstate can be prepared by reacting lithium iodide and tungsten hexafluoride in liquid sulfur dioxide.[3]

Physical properties

The compound has the LiSbF6 structure with unit cell parameters a=5.45 Å, α=57.4°.[4]

Chemical properties

Lithium hexafluorotungstenate is unstable and decomposes in a vacuum at 50 °C. It can react in an alkaline solution of hypochlorite as follows:[5]

2 LiWF6 + ClO− + 14 OH− → 2 Li+ + 2 WO42− + Cl− + 12 F− + 7 H2O
