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.{{cite book | title=Handbuch der präparativen anorganischen Chemie / 1. | publication-place=Stuttgart | isbn=3-432-02328-6 | oclc=310719485 | language=de | page=686}}

:\mathrm{ClC_6H_4SiH_3 + HI \longrightarrow C_6 H_5 Cl + SiH_3I}

Properties

At low temperatures, iodosilant quickly reacts with [Co(CO)4]− to form SiH3Co(CO)4.{{cite journal|journal=Chem. Commun. (London)|issue=11|language=en|issn=0009-241X|date=1965|pages=217|doi=10.1039/C19650000217|title=A volatile silicon–transition-metal compound|author=B. J. Aylett, J. M. Campbell}}
