Tin(IV) iodide, also known as stannic iodide, is the chemical compound with the formula SnI4. This tetrahedral molecule crystallises as a bright orange solid that dissolves readily in nonpolar solvents such as benzene.[1]
The compound is usually prepared by the reaction of iodine and tin:[2]
The compound hydrolyses in water.[3] In aqueous hydroiodic acid, it reacts to form a rare example of a metal hexaiodide:[2]
- SnI4 + 2 I− → [SnI6]2−
