The structure described by AlH3 crystallizes in the cubic Fd-3m space group. Al(1) is bonded to six equivalent H(1) atoms to form corner-sharing AlH6 octahedra. The corner-sharing octahedral tilt angles are 43°. H(1) is bonded in a bent 150 degrees geometry to two equivalent Al(1) atoms. is represented by the CIF card [CIF]
