Diboron

Diboron is a chemical compound consisting of two boron atoms. It is a stable molecule that exists in the gas phase. Diboron is a key intermediate in the production of boron compounds, and it is also used in the synthesis of organic compounds.

Structure and Bonding

Diboron is a diatomic molecule with a triple bond between the two boron atoms. The boron atoms are sp hybridized, and the molecule has a linear geometry. The bond length is 1.59 Å, which is shorter than the single bond length in boron monohydride (1.75 Å) but longer than the triple bond length in boron nitride (1.30 Å).

Synthesis

Diboron can be synthesized by the reaction of boron trichloride with lithium aluminum hydride. The reaction proceeds via the formation of a boron-aluminum complex, which then decomposes to give diboron and aluminum chloride.

Applications

Diboron is used in the synthesis of organic compounds, where it serves as a source of boron. It is also used in the production of boron compounds, such as boron nitride and boron carbide.
