The compound described by CaAgO2 crystallizes in the orthorhombic Cmmm space group. Ca(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CaO6 octahedra that share corners with six equivalent Ca(1)O6 octahedra, edges with four equivalent Ca(1)O6 octahedra, edges with four equivalent Ag(1)O6 octahedra, and edges with four equivalent Ag(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 13-14°. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form AgO6 octahedra that share corners with six equivalent Ag(2)O6 octahedra, edges with two equivalent Ag(1)O6 octahedra, edges with two equivalent Ag(2)O6 octahedra, and edges with eight equivalent Ca(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-10°. In the second Ag site, Ag(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form AgO6 octahedra that share corners with six equivalent Ag(1)O6 octahedra, edges with two equivalent Ag(1)O6 octahedra, edges with two equivalent Ag(2)O6 octahedra, and edges with eight equivalent Ca(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-10°. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Ca(1), one Ag(1), and one Ag(2) atom to form distorted OCa4Ag2 octahedra that share corners with six equivalent O(1)Ca4Ag2 octahedra, edges with four equivalent O(1)Ca4Ag2 octahedra, and edges with eight equivalent O(2)Ca2Ag4 octahedra. The corner-sharing octahedra are not tilted. In the second O site, O(2) is bonded to two equivalent Ca(1), two equivalent Ag(1), and two equivalent Ag(2) atoms to form OCa2Ag4 octahedra that share corners with six equivalent O(2)Ca2Ag4 octahedra, edges with four equivalent O(2)Ca2Ag4 octahedra, and edges with eight equivalent O(1)Ca4Ag2 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
