The structure described by MgZn2(FeO3)2 crystallizes in the trigonal R-3 space group. Mg(1) is bonded to six equivalent O(1) atoms to form MgO6 octahedra that share corners with six equivalent Fe(1)O6 octahedra and faces with two equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles are 42°. Fe(1) is bonded to six equivalent O(1) atoms to form distorted FeO6 octahedra that share corners with three equivalent Mg(1)O6 octahedra, edges with three equivalent Fe(1)O6 octahedra, and  a faceface with one Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles are 42°. Zn(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. O(1) is bonded to one Mg(1), two equivalent Fe(1), and one Zn(1) atom to form a mixture of distorted corner and edge-sharing OMgZnFe2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
