Ammonium hexafluorogallate is an inorganic chemical compound with the chemical formula (NH4)3GaF6. [1] [2]
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]
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]
