Ammonium hexafluorogallate is an inorganic chemical compound with the chemical formula (NH4)3GaF6.[1][2]
Synthesis
[edit]A mechanochemical reaction between ammonium fluoride and gallium fluoride trihydrate (GaF3·3H2O) at a ratio of 3:1 produces the compound.[3]
Also, a reaction of gallium(III) hydroxide, HF, and ammonium fluoride.[4]
- Ga(OH)3 + 3 HF + 3 NH4F → (NH)3GaF6 + 3 H2O[5]
Physical properties
[edit]Ammonium hexafluorogallate occurs in two polymorphic forms: tetragonal at low temperature and cubic at high temperature, with both transforming reversibly.[6]
Colorless crystals, soluble in water.[7]
