CaAgO2 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 Ag(1)O6 octahedra. The corner-sharing octahedra are not tilted. Ag(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form AgO6 octahedra that share corners with six equivalent Ag(1)O6 octahedra, edges with four equivalent Ag(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 Ag(1) atoms to form OCa2Ag4 octahedra that share corners with six equivalent O(1)Ca2Ag4 octahedra, edges with four equivalent O(1)Ca2Ag4 octahedra, and edges with eight equivalent O(2)Ca4Ag2 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 Ag(1) atoms to form OCa4Ag2 octahedra that share corners with six equivalent O(2)Ca4Ag2 octahedra, edges with four equivalent O(2)Ca4Ag2 octahedra, and edges with eight equivalent O(1)Ca2Ag4 octahedra. The corner-sharing octahedra are not tilted.
