The compound described by NiCdO2 is Caswellsilverite-like structured and crystallizes in the tetragonal P4/mmm space group. Ni(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form NiO6 octahedra that share corners with six equivalent Ni(1)O6 octahedra, edges with four equivalent Ni(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 Ni(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 Ni(1) and four equivalent Cd(1) atoms to form OCd4Ni2 octahedra that share corners with six equivalent O(1)Cd4Ni2 octahedra, edges with four equivalent O(1)Cd4Ni2 octahedra, and edges with eight equivalent O(2)Cd2Ni4 octahedra. The corner-sharing octahedra are not tilted. In the second O site, O(2) is bonded to four equivalent Ni(1) and two equivalent Cd(1) atoms to form OCd2Ni4 octahedra that share corners with six equivalent O(2)Cd2Ni4 octahedra, edges with four equivalent O(2)Cd2Ni4 octahedra, and edges with eight equivalent O(1)Cd4Ni2 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
