Ammonium hexafluoroindate is an inorganic chemical compound with the chemical formula (NH4)3InF6. [1] [2]
The compound can be obtained by reacting ammonium fluoride and indium bromide in anhydrous methanol, or by reacting ammonium fluoride and indium fluoride in aqueous solution. [3]
Also, a reaction involving indium hydroxide and ammonium fluoride: [4]
The compound decomposes at 120–170 °C to obtain NH4InF4, and further decomposes to InF3 at 185–300 °C. [5]
Ammonium hexafluoroindiate forms colorless crystals of tetragonal system, space group P4mnc, [6] insoluble in water. [4]
At 80 °C, a phase transition into the cubic phase occurs.
