Iodosilane is a chemical compound of silicon, hydrogen, and iodine. It is a colorless monoclinic crystal of space group P21/c at −157 °C.[1]
Preparation
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.[3]

Properties
At low temperatures, iodosilant quickly reacts with [Co(CO)4]− to form SiH3Co(CO)4.[4]
