The material structure described by NaErO2 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 Er(1)O6 octahedra, edges with six equivalent Na(1)O6 octahedra, and edges with six equivalent Er(1)O6 octahedra. The corner-sharing octahedral tilt angles are 8°. Er(1) is bonded to six equivalent O(1) atoms to form ErO6 octahedra that share corners with six equivalent Na(1)O6 octahedra, edges with six equivalent Na(1)O6 octahedra, and edges with six equivalent Er(1)O6 octahedra. The corner-sharing octahedral tilt angles are 8°. O(1) is bonded to three equivalent Na(1) and three equivalent Er(1) atoms to form a mixture of corner and edge-sharing ONa3Er3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
