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]

${\displaystyle {\ce {3TcO2 + 4F2 -> 2TcO3F + TcF6}}}$

• Dissolution of ammonium pertechnetate in anhydrous hydrogen fluoride:

${\displaystyle {\ce {NH4TcO4 + 2HF -> TcO3F + NH4F + H2O}}}$

Physical properties

The compound forms a yellow substance.^[4]

Chemical properties

The compound can be hydrolyzed to produce pertechnetic acid and hydrofluoric acid.

${\displaystyle {\ce {TcO3F + H2O -> HTcO4 + HF}}}$

It also reacts with arsenic pentafluoride or antimony pentafluoride.^[5]
