The material structure described by CaCdO2 is Caswellsilverite-like structured and crystallizes in the tetragonal P4/mmm space group. Ca(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CaO6 octahedra that share corners with six equivalent Ca(1)O6 octahedra, edges with four equivalent Ca(1)O6 octahedra, and edges with eight equivalent Cd(1)O6 octahedra. The corner-sharing octahedra are not tilted. Cd(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CdO6 octahedra that share corners with six equivalent Cd(1)O6 octahedra, edges with four equivalent Cd(1)O6 octahedra, and edges with eight equivalent Ca(1)O6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ca(1) and four equivalent Cd(1) atoms to form OCa2Cd4 octahedra that share corners with six equivalent O(1)Ca2Cd4 octahedra, edges with four equivalent O(1)Ca2Cd4 octahedra, and edges with eight equivalent O(2)Ca4Cd2 octahedra. The corner-sharing octahedra are not tilted. In the second O site, O(2) is bonded to four equivalent Ca(1) and two equivalent Cd(1) atoms to form OCa4Cd2 octahedra that share corners with six equivalent O(2)Ca4Cd2 octahedra, edges with four equivalent O(2)Ca4Cd2 octahedra, and edges with eight equivalent O(1)Ca2Cd4 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
