The compound is usually prepared by the reaction of iodine and tin:Therald Moeller, Delwin C. Edwards, "Tin(IV) Iodide (Stannic Iodide)" Inorganic Syntheses, 1953 volume IV, pp. 119-121] :Sn + 2 I₂ → SnI₄ The compound hydrolyses in water. In aqueous hydroiodic acid, it reacts to form a rare example of a metal hexaiodide:: SnI₄ + 2 I⁻ → [SnI₆] ²⁻
