borane
Electron-deficient molecule
Borane is a compound of boron and hydrogen.
The simplest, BH₃, is highly reactive and exists only fleetingly.
More stable boranes like diborane (B₂H₆) serve as reducing agents and catalysts in organic chemistry.
The term covers the entire family of boron hydrides, which have unusual bonding structures that defied early chemical theory.
