Infobox references

Boron triiodide is a chemical compound of boron and iodine with chemical formula BI3. It has a trigonal planar molecular geometry. It is a crystalline solid, which reacts vigorously with water to form boric acid.[2] Its dielectric constant is 5.38 and its heat of vaporization is 40.5 kJ/mol. At extremely high pressures, BI3 becomes metallic at ~23 GPa and is a superconductor above ~27 GPa. [3]

Preparation

Boron triiodide can be prepared by the reaction of boron with iodine at 209.5 °C or 409.1 °F.
