The material described by Ag2O3 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to one O(2), two equivalent O(1), and three equivalent O(3) atoms to form a mixture of corner and edge-sharing AgO6 octahedra. The corner-sharing octahedral tilt angles range from 0-13°. In the second Ag site, Ag(2) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form a mixture of corner and edge-sharing AgO6 octahedra. The corner-sharing octahedral tilt angles range from 0-55°. There are four inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ag(2) and four equivalent Ag(1) atoms to form OAg6 octahedra that share corners with four equivalent O(3)Ag5 square pyramids, edges with two equivalent O(1)Ag6 octahedra, and edges with six equivalent O(3)Ag5 square pyramids. In the second O site, O(2) is bonded in a trigonal non-coplanar geometry to one Ag(1) and two equivalent Ag(2) atoms. In the third O site, O(3) is bonded to two equivalent Ag(2) and three equivalent Ag(1) atoms to form OAg5 square pyramids that share corners with two equivalent O(1)Ag6 octahedra, edges with three equivalent O(1)Ag6 octahedra, and edges with four equivalent O(3)Ag5 square pyramids. The corner-sharing octahedral tilt angles are 9°. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to two equivalent Ag(2) atoms. is represented by the CIF file [CIF]
