NaDyO2 crystallizes in the tetragonal I4_1/amd space group. Na(1) is bonded to six O(1,1) atoms to form distorted NaO6 octahedra that share corners with two equivalent Dy(1)O6 octahedra, corners with four equivalent Na(1)O6 octahedra, edges with four equivalent Na(1)O6 octahedra, and edges with eight equivalent Dy(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-14°. Dy(1) is bonded to six O(1,1,1) atoms to form DyO6 octahedra that share corners with two equivalent Na(1)O6 octahedra, corners with four equivalent Dy(1)O6 octahedra, edges with four equivalent Dy(1)O6 octahedra, and edges with eight equivalent Na(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-14°. There are four inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Na(1) and three equivalent Dy(1) atoms to form a mixture of distorted corner and edge-sharing ONa3Dy3 octahedra. The corner-sharing octahedral tilt angles range from 0-14°. In the second O site, O(1) is bonded to three equivalent Na(1) and three equivalent Dy(1) atoms to form a mixture of distorted corner and edge-sharing ONa3Dy3 octahedra. The corner-sharing octahedral tilt angles range from 0-14°. In the third O site, O(1) is bonded to three equivalent Na(1) and three equivalent Dy(1) atoms to form a mixture of distorted corner and edge-sharing ONa3Dy3 octahedra. The corner-sharing octahedral tilt angles range from 0-14°. In the fourth O site, O(1) is bonded to three equivalent Na(1) and three equivalent Dy(1) atoms to form a mixture of distorted corner and edge-sharing ONa3Dy3 octahedra. The corner-sharing octahedral tilt angles range from 0-14°.
