borane




A covalent hydride of boron, of unusual molecular structure. Boranes have hydrogen-bridge bonding, and the boron atoms form the vertices of polyhedra. Boranes are volatile, reactive, and often flammable in air. They may be used as high-energy fuels for rockets and jet planes.

The simplest borane is B2H6, made by treating magnesium boride with acid. The higher boranes have up to 10 boron atoms.
