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

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.

${\displaystyle \mathrm {ClC_{6}H_{4}SiH_{3}+HI\longrightarrow C_{6}H_{5}Cl+SiH_{3}I} }$

Properties

At low temperatures, iodosilant quickly reacts with to form SiH₃Co(CO)₄.
