Ammonium hexafluorogallate is an inorganic chemical compound with the chemical formula (NH
4)
3GaF
6.[1][2]
Synthesis
A mechanochemical reaction between ammonium fluoride and gallium fluoride trihydrate (GaF
3·3H
2O) 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 NH
4F → (NH)
3GaF
6 + 3 H
2O[5]
- Ga(OH)
Physical properties
Ammonium hexafluorogallate occurs in two polymorphic forms: tetragonal at low temperature and cubic at high temperature, with both transforming reversibly.[6]
It has colorless crystals, which are soluble in water.[7]
