Silicon tetraiodide

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).This compound is produced by treating silicon-copper mixture with iodine:[3] It reacts quickly with water and moisture in the air.Of more academic interest is the reaction of silane with iodine vapour at 130 - 150 °C, as this produces a series of compounds ranging from iodosilane SiH3I to diiodosilane SiH2I2 and triiodosilane SiHI3 as well.[4] The last one can be readily distinguished from the similar carbon compound, iodoform which is a yellow solid at room temperature.
NFPA 704 four-colored diamond Health 2: Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury. E.g. chloroform Flammability 0: Will not burn. E.g. water Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazards (white): no code
