Lithium hexafluoroarsenate is an inorganic chemical compound with the chemical formula LiAsF6.[1][2][3]

Synthesis

[edit]

Reaction of arsenic pentafluoride and lithium fluoride in liquid hydrogen fluoride:

LiF + AsF5 → LiAsF6

Physical properties

[edit]

Lithium hexafluoroarsenate forms crystals. It is well-soluble both in water and organic solvents.[4][5] It forms a crystallohydrate of the composition Li[AsF6]•H2O. Its crystals are of rhombic system.[6]

Chemical properties

[edit]

Strong oxidizing and reducing agents as well as strong acids and bases cause violent reactions with lithium hexafluoroarsenate. The decomposition produces hydrogen fluoride, arsenic oxides, and lithium oxide.

Uses

[edit]

Lithium hexafluoroarsenate can be used in the fabrication of lithium-ion batteries.[7][8]
