The compound described by LiAlO2 is beta beryllia-derived structured and crystallizes in the tetragonal P4_12_12 space group. Li(1) is bonded to four equivalent O(1) atoms to form LiO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra, corners with six equivalent Al(1)O4 tetrahedra, and  an edgeedge with one Al(1)O4 tetrahedra. Al(1) is bonded to four equivalent O(1) atoms to form AlO4 tetrahedra that share corners with four equivalent Al(1)O4 tetrahedra, corners with six equivalent Li(1)O4 tetrahedra, and  an edgeedge with one Li(1)O4 tetrahedra. O(1) is bonded to two equivalent Li(1) and two equivalent Al(1) atoms to form a mixture of edge and corner-sharing OLi2Al2 tetrahedra. is represented by the CIF file [CIF]
