Caesium triiodide is an inorganic compound, with the chemical formula of CsI3. It can be prepared by slow volatilization and crystallization of caesium iodide and iodine in aqueous ethanol solution.[3] It can form precipitates with diazobenzene.[4]
It undergoes a phase transition from Pnma to P-3c1 under high pressure, and its structure changes from layered to 3D.[5]
