Technetium(III) iodide

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.

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.
