Aluminium hydride (also known as alane and alumane) refers to a collection of inorganic compounds with the formula Al H₃. As a gas, alane is a planar molecule. When generated in ether solutions, it exists as an ether adduct. Solutions of alane polymerizes to a solid, which exists in several crystallographically distinguishable forms.
