The material structure described by LiCd2Al4O8 crystallizes in the cubic F-43m space group. Li(1) is bonded to four equivalent Al(1) and four equivalent O(1) atoms to form LiAl4O4 tetrahedra that share corners with four equivalent Cd(1)O4 tetrahedra and corners with twelve equivalent O(2)Al3Cd trigonal pyramids. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded to four equivalent O(1) atoms to form CdO4 tetrahedra that share corners with four equivalent Li(1)Al4O4 tetrahedra. In the second Cd site, Cd(2) is bonded in a tetrahedral geometry to four equivalent O(2) atoms. Al(1) is bonded in a 7-coordinate geometry to one Li(1), three equivalent O(1), and three equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(2) is bonded to one Cd(2) and three equivalent Al(1) atoms to form distorted OAl3Cd trigonal pyramids that share corners with three equivalent Li(1)Al4O4 tetrahedra, corners with three equivalent O(2)Al3Cd trigonal pyramids, and edges with three equivalent O(2)Al3Cd trigonal pyramids. In the second O site, O(1) is bonded in a 5-coordinate geometry to one Li(1), one Cd(1), and three equivalent Al(1) atoms. is represented by the CIF file [CIF]
