Digallane (systematically named digallane(6)) is an inorganic compound with the chemical formula GaH₂(H)₂GaH₂ (also written [{GaH₂(μ-H)}₂] or [Ga₂H₆]). It is the dimer of the monomeric compound gallane. The eventual preparation of the pure compound, reported in 1989, was hailed as a "tour de force." Digallane had been reported as early as 1941 by Wiberg; however, this claim could not be verified by later work by Greenwood and others. This compound is a colorless gas that decomposes above 0 °C.
