Scandium perrhenate is an inorganic compound, with the chemical formula Sc(ReO4)3. Its thermal stability is lower than that of the corresponding compounds of the yttrium and lanthanum perrhenates.[2][3]
Preparation and properties
Scandium perrhenate can be obtained by reacting perrhenic acid with scandium oxide.[1] From the solution, the trihydrate of scandium perrhenate can be precipitated, which loses water at 50 °C to obtain Sc(ReO4)3·H2O, and obtains the anhydrous form at 140 °C. Scandium oxide and rhenium(VII) oxide are formed at 550 °C.[4]
Scandium perrhenate trihydrate is a crystal in the triclinic crystal system, with space group P1, a=7.333, b=7.985, c=20.825 Å; α=93.35, β=92.20, γ=97.42°.[5]
Scandium perrhenate can crystallize with ammonium perrhenate in water to form NH4Sc(ReO4)4·4H2O.[6]
