Thallium triiodide does exist and it is formulated as T l X + I X 3 X − and not T l X 3 + ( I X −) X 3. Thus T l I X 3 is a thallium (I) compound and contains the triiodide ion, I X 3 X −. This is confirmed by considering the standard potential which indicate that T l ( I I I) is rapidly reduced to T l ( I) by the iodide.
