The structure described by LiAlH2 crystallizes in the tetragonal I4_1/a space group. Li(1) is bonded in a linear geometry to two equivalent H(1) atoms. Al(1) is bonded in a distorted square co-planar geometry to four equivalent H(1) atoms. H(1) is bonded in a trigonal non-coplanar geometry to one Li(1) and two equivalent Al(1) atoms. is represented by the CIF file [CIF]
