Property

CAS No.: 13517-10-7 Formula: BI3 Molecular Weight: 391.52400

Description

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. 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.
