Iodine trichloride is an interhalogen compound of iodine and chlorine. It is bright yellow and in the solid state is present as a planar dimer I2Cl6, Cl2I(μ-Cl)2ICl2, with two bridging Cl atoms.[1]

It can be prepared by reacting iodine with an excess of liquid chlorine at −70 °C. In the melt it is conductive, which may indicate dissociation:[2]

I2Cl6 is in equilibrium with ICl2+ + ICl4

Iodine trichloride can be created by heating a mixture of liquid iodine and chlorine gas to 105 °C.

It is an oxidizing agent, capable of causing fire on contact with organic materials.
