Iodosilane is achemical compound ofsilicon,hydrogen, andiodine. It is a colorlessmonoclinic crystal of space group P2₁/c at −157 °C.^[1]

Iodosilane is the first product of the reaction betweenmonosilane and iodine, the other products beingdi-,tri- and finally tetraiodosilane (silicon tetraiodide).

It can also be produced by the reaction ofphenylsilane orchlorophenylsilane withhydrogen iodide.^[4]

${\displaystyle \mathrm{C}\mathrm{l}{\mathrm{C}}_6{\mathrm{H}}_4\mathrm{S}\mathrm{i}{\mathrm{H}}_3+\mathrm{H}\mathrm{I}⟶{\mathrm{C}}_6{\mathrm{H}}_5\mathrm{C}\mathrm{l}+\mathrm{S}\mathrm{i}{\mathrm{H}}_3\mathrm{I}}$

At low temperatures, iodosilane quickly reacts with [Co(CO)₄]⁻ to form SiH₃Co(CO)₄.^[5]
