Lithium hexafluoroarsenate is an inorganic chemical compound with the chemical formula LiAsF6.[1][2][3]
Reaction of arsenic pentafluoride and lithium fluoride in liquid hydrogen fluoride:
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]
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.
Lithium hexafluoroarsenate can be used in the fabrication of lithium-ion batteries.[7][8]
