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

• 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

The compound forms a yellow substance. ^[4]

Chemical properties

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]
