Stannic Iodosulphide, SnS₂I₄

Stannic Iodosulphide, SnS₂I₄, is said to be formed when stannic sulphide and iodine, in the theoretical proportions, are fused together in a stream of carbon dioxide. The product sublimes in yellowish red crystals, which are soluble in chloroform and carbon disulphide; but water decomposes the compound into stannic oxide, hydriodic acid, and sulphur.
