The crystal structure described by NaDyO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Na(1) is bonded to six equivalent O(1) atoms to form NaO6 octahedra that share corners with six equivalent Dy(1)O6 octahedra, edges with six equivalent Na(1)O6 octahedra, and edges with six equivalent Dy(1)O6 octahedra. The corner-sharing octahedral tilt angles are 8°. Dy(1) is bonded to six equivalent O(1) atoms to form DyO6 octahedra that share corners with six equivalent Na(1)O6 octahedra, edges with six equivalent Na(1)O6 octahedra, and edges with six equivalent Dy(1)O6 octahedra. The corner-sharing octahedral tilt angles are 8°. O(1) is bonded to three equivalent Na(1) and three equivalent Dy(1) atoms to form a mixture of edge and corner-sharing ONa3Dy3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF file [CIF]
