Pertechnetyl fluoride is an inorganic compound, a salt of technetium and hydrofluoric acid with the chemical formula TcO
3F. The compound was originally synthesized by H. Selig and G. Malm in 1963.[1][2]
Synthesis
[edit]- Effect of fluorine on technetium(IV) oxide at 150 °C:[3]
- 3 TcO2 + 4 F2 → 2 TcO3F + TcF6
- Dissolution of ammonium pertechnetate in anhydrous hydrogen fluoride:
- NH4TcO4 + 2 HF → TcO3F + NH4F + H2O
Physical properties
[edit]The compound forms a yellow substance.[4]
Chemical properties
[edit]The compound can be hydrolyzed to produce pertechnetic acid and hydrofluoric acid.
- TcO3F + H2O → HTcO4 + HF
It also reacts with arsenic pentafluoride or antimony pentafluoride.[5]
