Gallane
Gallane is an inorganic compound with the chemical formula GaH. It has been detected as a transient species in the gas phase; also at low temperature (3.5 K) following the reaction of laser ablated gallium atoms and dihydrogen, and more recently in an argon matrix doped with vapour over solid digallane, GaH.
