Diboron is a chemical compound of boron from the group of chlorides.

Production and representation

Diboron can be recovered in an electric discharge by the reaction of boron trichloride with a mercury or copper.

Properties

Diboron is a colorless liquid, which dissolves in water to form boric acid and hydrochloric acid.

Like the other Bortetrahalogenide it decomposes even at room temperature, the rate of decomposition increases under the catalytic influence of the decomposition products.

In air, the compound ignited immediately.

In the solid state, it has an orthorhombic crystal structure with space group Pbca. Diboron forms with donors D (eg hydrogen sulphide) adducts of the type B2Cl4 · 2D. Hydrogen reacts with the formation of dichloroborane.

Use

Diboron can also be used for the preparation of organo-boron compounds.
