MgMn2Zn2O6 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 Mn(1)O6 octahedra, and faces with two equivalent Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles are 43°. Mn(1) is bonded to six equivalent O(1) atoms to form MnO6 octahedra that share corners with nine equivalent Zn(1)O6 octahedra, edges with three equivalent Mg(1)O6 octahedra, edges with three equivalent Mn(1)O6 octahedra, and  a faceface with one Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-56°. 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 Mn(1)O6 octahedra, edges with three equivalent Zn(1)O6 octahedra,  a faceface with one Mg(1)O6 octahedra, and  a faceface with one Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-56°. O(1) is bonded to one Mg(1), two equivalent Mn(1), and two equivalent Zn(1) atoms to form a mixture of distorted edge and corner-sharing OMgMn2Zn2 trigonal bipyramids.
