Rubidium triiodide is an inorganic compound with the chemical formula RbI3. It is composed of Rb+ and I−
3. It can be obtained by heating rubidium iodide and iodine in aqueous solution.[1]
Rubidium triiodide is an orthorhombic black crystal, isomorphic to caesium triiodide, with space group Pnma, unit cell parameters a = 1090.8 pm, b = 665.5 pm, c = 971.1 pm.[2]
It has long been believed that rubidium triiodide reacts further with iodine to form RbI7 and RbI9,[3] but this has been refuted by recent studies.[4][5]
