Technetium pentafluoride is a binaryinorganic chemical compound oftechnetium metal andfluorine with the chemical formulaTcF
5.[1][2][3][4]
The compound can be synthesised by heating of technetium powder in a jet of fluorine diluted with nitrogen:
Another way to prepare it is the effect ofiodine ontechnetium hexafluoride solution iniodine pentafluoride:[5]
Technetium pentafluoride forms yellow crystals[6] of theorthorhombic crystal system.[7] It reacts with water, and is volatile.
The compound is hydrolyzed by water, disproportionating to more stable technetium compounds:
