Thallium triiodide is a chemical compound of thallium and iodine with formula TlI3. Unlike the other thallium trihalides, which contain thallium(III), TlI3 is a thallium(I) salt and contains the triiodide ion, I−3. An appreciation as to why Tl+ is not oxidised to Tl3+ in the reaction: Tl3+ + 2 I− → Tl+ + I2 can be gained by considering the standard reduction potentials of the half cells which are: Tl3+ + 2 e− → Tl+; Er° = 1.252I2 + 2 e− → 2 I−; Er° = 0.5355 The favoured reaction is therefore the reduction of Tl3+ to Tl+ (1.252 > 0.5355).

Unlike the other thallium trihalides, which contain thallium(III), TlI3 is a thallium(I) salt and contains the triiodide ion, I−3. An appreciation as to why Tl+ is not oxidised to Tl3+ in the reaction: Tl3+ + 2 I− → Tl+ + I2 can be gained by considering the standard reduction potentials of the half cells which are: Tl3+ + 2 e− → Tl+; Er° = 1.252I2 + 2 e− → 2 I−; Er° = 0.5355 The favoured reaction is therefore the reduction of Tl3+ to Tl+ (1.252 > 0.5355). Using standard electrode potentials in this way must be done with caution as factors such as complex formation and solvation may affect the reaction. TlI3 is no exception as it is possible to stabilise thallium(III) with excess I− forming the TlI−4 ion (isoelectronic with the tetraiodomercurate anion and with ). (en)
  • Il triioduro di tallio è un composto del tallio e dello iodio con formula TlI3. È formato dagli ioni Tl+ e I3-. A differenza degli altri trialogenuri di tallio,che contengono tallio (III), il triioduro di tallio è un sale di tallio(I) e contiene lo ione triioduro. Viene sintetizzato facendo evaporare una soluzione acquosa di Tl+ e I2 in ioduro di idrogeno (HI) concentrato. Diversamente dagli altri trialogenuri di tallio non si può ottenere Tl3+(I-)3 poiché i potenziali di riduzione delle coppie Tl3+/Tl+ e I2/2I- fanno sì che lo iodio riduca il tallio a monopositivo. Un eccesso di iodio non sposta ulteriormente la reazione verso i prodotti, ma stabilizza il tallio tripositivo per formazione del complesso [TlI4]-: con con Pertanto la reazione favorita è la riduzione di TI3+ a TI+ (1,252>0,5355). In ambiente debolmente alcalino precipita l'ossido di tallio(III): La molecola di TlI3 non segue la regola dell'ottetto, per cui è una molecola ipervalente. (it)
