Digallane

Digallane (systematically named digallane(6) and di-μ-hydrido-bis(dihydridogallium)) is an inorganic compound with the chemical formula GaH
2(H)
2GaH
2 (also written [{GaH
2(μ-H)}
2] or [Ga
2H
6]). 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.
