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. It can also be prepared by this other method: 3 HI + BCl3 --> BI3 + 3 HCl (this reaction requires high temperature).
