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 of iodine on technetium hexafluoride solution in iodine pentafluoride:[5]
Technetium pentafluoride forms yellow crystals[6] of orthorhombic crystal system.[7] It reacts with water, and is volatile.
The compound is hydrolyzed by water, disproportionating to more stable technetium compounds:
