The compound described by DyMn2O4 is Aluminum carbonitride-like structured and crystallizes in the trigonal R-3m space group. Dy(1) is bonded to six equivalent O(1) atoms to form distorted DyO6 octahedra that share corners with six equivalent Mn(1)O5 trigonal bipyramids and edges with six equivalent Dy(1)O6 octahedra. Mn(1) is bonded to one O(1) and four equivalent O(2) atoms to form MnO5 trigonal bipyramids that share corners with three equivalent Dy(1)O6 octahedra, corners with six equivalent Mn(1)O5 trigonal bipyramids, and edges with three equivalent Mn(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 64°. 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 ODy3Mn tetrahedra that share corners with nine equivalent O(1)Dy3Mn tetrahedra, corners with four equivalent O(2)Mn4 trigonal pyramids, and edges with three equivalent O(1)Dy3Mn tetrahedra. In the second O site, O(2) is bonded to four equivalent Mn(1) atoms to form OMn4 trigonal pyramids that share corners with four equivalent O(1)Dy3Mn tetrahedra, corners with six equivalent O(2)Mn4 trigonal pyramids, and edges with three equivalent O(2)Mn4 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
