Silicon iodide is the chemical compound with the formula SiI4. It is a tetrahedral molecule with Si-I bond lengths of 2.432(5) Å.[1]

SiI4 is a precursor to silicon amides of the formula Si(NR2)4 (R = alkyl).[2]It has also been of interest in the manufacture and etching of silicon in microelectronics.
