LiZn(FeO2)4 is Spinel-derived structured and crystallizes in the trigonal R3m space group. Li(1) is bonded to one O(4) and three equivalent O(3) atoms to form LiO4 tetrahedra that share corners with three equivalent Zn(1)O6 octahedra and corners with nine equivalent Fe(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 56-60°. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to one O(2) and three equivalent O(1) atoms to form FeO4 tetrahedra that share corners with three equivalent Zn(1)O6 octahedra and corners with nine equivalent Fe(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 57-60°. In the second Fe site, Fe(2) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms to form FeO6 octahedra that share corners with three equivalent Li(1)O4 tetrahedra, corners with three equivalent Fe(1)O4 tetrahedra, edges with two equivalent Zn(1)O6 octahedra, and edges with four equivalent Fe(2)O6 octahedra. Zn(1) is bonded to three equivalent O(1) and three equivalent O(3) atoms to form ZnO6 octahedra that share corners with three equivalent Li(1)O4 tetrahedra, corners with three equivalent Fe(1)O4 tetrahedra, and edges with six equivalent Fe(2)O6 octahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to one Fe(1), two equivalent Fe(2), and one Zn(1) atom. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to one Fe(1) and three equivalent Fe(2) atoms. In the third O site, O(3) is bonded in a rectangular see-saw-like geometry to one Li(1), two equivalent Fe(2), and one Zn(1) atom. In the fourth O site, O(4) is bonded in a distorted rectangular see-saw-like geometry to one Li(1) and three equivalent Fe(2) atoms.
