The material structure described by LiZn2Al4O8 crystallizes in the orthorhombic Imm2 space group. Li(1) is bonded to two equivalent O(2) and two equivalent O(4) atoms to form distorted LiO4 tetrahedra that share corners with four equivalent Zn(1)O5 square pyramids, corners with two equivalent Al(1)O4 tetrahedra, and  an edgeedge with one Al(3)O4 tetrahedra. Zn(1) is bonded to one O(3), two equivalent O(1), and two equivalent O(4) atoms to form distorted ZnO5 square pyramids that share corners with two equivalent Li(1)O4 tetrahedra, corners with two equivalent Al(1)O4 tetrahedra, corners with three equivalent Al(3)O4 tetrahedra, and edges with two equivalent Zn(1)O5 square pyramids. There are three inequivalent Al sites. In the first Al site, Al(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form AlO4 tetrahedra that share corners with four equivalent Zn(1)O5 square pyramids and corners with two equivalent Li(1)O4 tetrahedra. In the second Al site, Al(2) is bonded in a 5-coordinate geometry to one O(1), two equivalent O(2), and two equivalent O(3) atoms. In the third Al site, Al(3) is bonded to two equivalent O(3) and two equivalent O(4) atoms to form AlO4 tetrahedra that share corners with six equivalent Zn(1)O5 square pyramids and  an edgeedge with one Li(1)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to two equivalent Zn(1), one Al(1), and one Al(2) atom. In the second O site, O(2) is bonded to one Li(1), one Al(1), and two equivalent Al(2) atoms to form distorted OLiAl3 trigonal pyramids that share corners with two equivalent O(4)LiAlZn2 tetrahedra, corners with four equivalent O(3)Al3Zn tetrahedra,  a cornercorner with one O(2)LiAl3 trigonal pyramid, and  a faceface with one O(2)LiAl3 trigonal pyramid. In the third O site, O(3) is bonded to one Zn(1), one Al(3), and two equivalent Al(2) atoms to form OAl3Zn tetrahedra that share  a cornercorner with one O(3)Al3Zn tetrahedra, corners with four equivalent O(4)LiAlZn2 tetrahedra, corners with four equivalent O(2)LiAl3 trigonal pyramids, and  an edgeedge with one O(3)Al3Zn tetrahedra. In the fourth O site, O(4) is bonded to one Li(1), two equivalent Zn(1), and one Al(3) atom to form distorted OLiAlZn2 tetrahedra that share corners with four equivalent O(3)Al3Zn tetrahedra, corners with two equivalent O(2)LiAl3 trigonal pyramids, and edges with two equivalent O(4)LiAlZn2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
