Iodosilane is a chemical compound of silicon, hydrogen, and iodine. It is a colorless monoclinic crystal of space group P2<sub>1</sub>/c at âÂÂ157 ðC.
Iodosilane is the first product of the reaction between monosilane and iodine, the other products being di-, tri- and finally tetraiodosilane (silicon tetraiodide).
It can also be produced by the reaction of phenylsilane or chlorophenylsilane with hydrogen iodide.
At low temperatures, iodosilane quickly reacts with [Co(CO)<sub>4</sub>]<sup>âÂÂ</sup> to form SiH<sub>3</sub>Co(CO)<sub>4</sub>.
