Iodine trichloride is a 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 → ICl2+ + ICl4−
