Technetium(III) iodide is an inorganic compound with the chemical formula TcI3. It is the first iodide of technetium discovered and was first reported in 2013. Theoretical studies have shown that a single layer of TcI3 is ferromagnetic.[1]

It can be obtained by the reaction of Tc2(CH3COO)4Cl2 and hydrogen iodide at 150 °C, or by the reaction of technetium and iodine at 300~400 °C. It decomposes in a vacuum at 450 °C to produce the metal technetium.[2]
