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