The structure described by MgDyMn2O4 is Corundum-derived structured and crystallizes in the trigonal R-3m space group. Mg(1) is bonded to six equivalent O(2) atoms to form edge-sharing MgO6 octahedra. Dy(1) is bonded to six equivalent O(1) atoms to form edge-sharing DyO6 octahedra. Mn(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1) and three equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Dy(1) and one Mn(1) atom to form distorted ODy3Mn trigonal pyramids that share corners with three equivalent O(2)Mg3Mn3 octahedra, corners with nine equivalent O(1)Dy3Mn trigonal pyramids, and edges with three equivalent O(1)Dy3Mn trigonal pyramids. The corner-sharing octahedral tilt angles are 57°. In the second O site, O(2) is bonded to three equivalent Mg(1) and three equivalent Mn(1) atoms to form OMg3Mn3 octahedra that share corners with three equivalent O(2)Mg3Mn3 octahedra, corners with three equivalent O(1)Dy3Mn trigonal pyramids, and edges with nine equivalent O(2)Mg3Mn3 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
