Technetium pentafluoride has the formula unit TcF5.
Technetium pentafluoride is used in nuclear medicine for labeling compounds for imaging purposes, particularly in radioisotope scans. It can also be used in research laboratories for studying technetium chemistry and its properties.
Technetium is an element and therefore does not contain any compounds! If the questioner meant to ask, "What are 3 compounds of technetium", that is a different question. The following compounds are listed on a web site with no obvious copyright notices:Technetium hexafluoride: TcF6Technetium pentafluoride: TcF5Technetium hexachloride: TcCl6Technetium tetrachloride: TcCl4Technetium tetrabromide: TcBr4Technetium dioxide: TcO2Ditechnetium heptoxide: Tc2O7Technetium disulphide: TcS2Ditechnetium decacarbonyl: Tc2(CO)10
