Caesium triiodide is an inorganic compound with chemical formula Cs+[I3]−. It can be prepared by slow volatilization and crystallization of caesium iodide and iodine in aqueous ethanol solution.[4]
It undergoes a phase transition from Pnma to P-3c1 under high pressure, and its structure changes from layered to 3D.[5]
