Hexaiodobenzene is a chemical compound with the formula C6I6. Structurally, it is a derivative of benzene, in which all hydrogen atoms are replaced by iodine atoms. It forms orange crystals[1] that are poorly soluble in all solvents.
The compound was first prepared by iodination of benzoic acid in the presence of hot fuming sulfuric acid.[2] It adopts the expected structure with a central C6 ring.[3]
