The thallium halides come in two oxidation states: monohalides, where thallium has the oxidation state +1, and trihalides, where thallium generally has oxidation state +3.

Monohalides[change | change source]

Thallium(I) iodide has a distorted rock salt structure

The monohalides all contain thallium with oxidation state +1.

Trihalides[change | change source]

Thallium(III) halides are very rare. Some of them are unstable. The thallium(III) iodide does not form. They are quite different to aluminium, gallium and indium trihalides.
