KAlH4 crystallizes in the tetragonal I4_1/a space group. K(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 single-bond geometry to two equivalent K(1) and one Al(1) atom.
KAlH4 crystallizes in the tetragonal I4_1/a space group. K(1) is bonded in a 8-coordinate geometry to eight equivalent H(1) atoms. There are four shorter (2.68 Å) and four longer (2.74 Å) K(1)-H(1) bond lengths. Al(1) is bonded in a tetrahedral geometry to four equivalent H(1) atoms. All Al(1)-H(1) bond lengths are 1.62 Å. H(1) is bonded in a distorted single-bond geometry to two equivalent K(1) and one Al(1) atom.
