The compound described by NaAlH4 is Zircon-like structured and crystallizes in the tetragonal I4_1/a space group. Na(1) is bonded in a 8-coordinate geometry to eight equivalent H(1) atoms. Al(1) is bonded in a tetrahedral geometry to four equivalent H(1) atoms. H(1) is bonded in a distorted trigonal planar geometry to two equivalent Na(1) and one Al(1) atom. is represented by the CIF card [CIF]
