ZnFe2O4 is Spinel-like structured and crystallizes in the orthorhombic Imma space group. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form FeO4 tetrahedra that share corners with six equivalent Fe(2)O6 octahedra and corners with six equivalent Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 54-58°. In the second Fe site, Fe(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form FeO6 octahedra that share corners with six equivalent Fe(1)O4 tetrahedra, edges with two equivalent Fe(2)O6 octahedra, and edges with four equivalent Zn(1)O6 octahedra. Zn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form ZnO6 octahedra that share corners with six equivalent Fe(1)O4 tetrahedra, edges with two equivalent Zn(1)O6 octahedra, and edges with four equivalent Fe(2)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to one Fe(1), one Fe(2), and two equivalent Zn(1) atoms. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Fe(1), two equivalent Fe(2), and one Zn(1) atom.
