Carbon tetraiodide is CI4, a tetrahalomethane. Being bright red, it is a relatively rare example of a highly colored methane derivative. It is only 2% by weight carbon, although other methane derivatives are known with still less carbon.

Diphosphorus tetraiodide, p2i4, is an orange crystalline solid, and a versatile reducing agent. The phosphorus atom has an nmr chemical shift of about 100 ppm (downfield of h3po4).

It is red to orange-red cubic crystal. 4. 322g/cm3 density. 144 ° c melting point. Dissolved in water and decomposition. Soluble methanol, benzene, carbon tetrachloride, carbon disulfide. Case of ethanol and acetone break down. Carbon dioxide as a carrier, iodine through metal germanium powder heated above about 560 ° c reaction in the system.

Silicon tetraiodide is the chemical compound with the formula sii4. It is a tetrahedral molecule with si-i bond lengths of 2. 432(5)

Tellurium tetraiodide (TeI4) is an inorganic chemical compound. It has a tetrameric structure which is different from the tetrameric solid forms of TeCl4 and TeBr4.[1] In TeI4 the Te atoms are octahedrally coordinated and edges of the octahedra are shared.

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
