The material 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 Zn(1)O6 octahedra, edges with six equivalent Fe(1)O6 octahedra, and faces with two equivalent Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles are 44°. Fe(1) is bonded to six equivalent O(1) atoms to form distorted FeO6 octahedra that share corners with nine equivalent Zn(1)O6 octahedra, edges with three equivalent Mg(1)O6 octahedra, edges with three equivalent Fe(1)O6 octahedra, and  a faceface with one Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-56°. Zn(1) is bonded to six equivalent O(1) atoms to form ZnO6 octahedra that share corners with three equivalent Mg(1)O6 octahedra, corners with nine equivalent Fe(1)O6 octahedra, edges with three equivalent Zn(1)O6 octahedra,  a faceface with one Mg(1)O6 octahedra, and  a faceface with one Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-56°. O(1) is bonded to one Mg(1), two equivalent Fe(1), and two equivalent Zn(1) atoms to form a mixture of distorted edge and corner-sharing OMgZn2Fe2 trigonal bipyramids. is represented by the CIF card [CIF]
