Gallium perrhenate is an inorganic compound with the chemical formula of Ga(ReO4)3. It exists in the anhydrous and hydrate forms.

Preparation

Gallium can be anodically dissolved in perrhenic acid at 50-55 °C, and dried with sulfuric acid to obtain the hydrate crystal [Ga(H2O)6(ReO4)3]·2H2O.[1] The anhydrous form can be obtained by reacting gallium(III) oxide and rhenium(VII) oxide at 450 °C.[2]

Chemical properties

Gallium perrhenate decomposes above 300 °C to form rhenium(VII) oxide and gallium(III) oxide:[3]

2 Ga(ReO4)3 → 3 Re2O7 + Ga2O3
