NaCdO2 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 Cd(1)O6 octahedra, edges with six equivalent Na(1)O6 octahedra, and edges with six equivalent Cd(1)O6 octahedra. The corner-sharing octahedral tilt angles are 5°. Cd(1) is bonded to six equivalent O(1) atoms to form CdO6 octahedra that share corners with six equivalent Na(1)O6 octahedra, edges with six equivalent Na(1)O6 octahedra, and edges with six equivalent Cd(1)O6 octahedra. The corner-sharing octahedral tilt angles are 5°. O(1) is bonded to three equivalent Na(1) and three equivalent Cd(1) atoms to form a mixture of corner and edge-sharing ONa3Cd3 octahedra. The corner-sharing octahedra are not tilted.
