K2LiAlH6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. K(1) is bonded to twelve equivalent H(1) atoms to form KH12 cuboctahedra that share corners with twelve equivalent K(1)H12 cuboctahedra, faces with six equivalent K(1)H12 cuboctahedra, faces with four equivalent Li(1)H6 octahedra, and faces with four equivalent Al(1)H6 octahedra. Li(1) is bonded to six equivalent H(1) atoms to form LiH6 octahedra that share corners with six equivalent Al(1)H6 octahedra and faces with eight equivalent K(1)H12 cuboctahedra. The corner-sharing octahedra are not tilted. Al(1) is bonded to six equivalent H(1) atoms to form AlH6 octahedra that share corners with six equivalent Li(1)H6 octahedra and faces with eight equivalent K(1)H12 cuboctahedra. The corner-sharing octahedra are not tilted. H(1) is bonded in a distorted linear geometry to four equivalent K(1), one Li(1), and one Al(1) atom.
