The compound described by LiAlAsO4 crystallizes in the tetragonal I-4 space group. Li(1) is bonded to four equivalent O(1) atoms to form LiO4 tetrahedra that share corners with four equivalent Al(1)O4 tetrahedra and corners with four equivalent As(1)O4 tetrahedra. Al(1) is bonded to four equivalent O(1) atoms to form AlO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra and corners with four equivalent As(1)O4 tetrahedra. As(1) is bonded to four equivalent O(1) atoms to form AsO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra and corners with four equivalent Al(1)O4 tetrahedra. O(1) is bonded in a trigonal non-coplanar geometry to one Li(1), one Al(1), and one As(1) atom. is represented by the CIF card [CIF]
