The material structure described by Zn(AgO2)2 is Spinel-like structured and crystallizes in the trigonal R3m space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to one O(2) and three equivalent O(1) atoms to form AgO4 tetrahedra that share corners with three equivalent Zn(2)O6 octahedra and corners with nine equivalent Ag(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 57-61°. In the second Ag site, Ag(2) is bonded to one O(2), one O(3), two equivalent O(1), and two equivalent O(4) atoms to form AgO6 octahedra that share corners with three equivalent Ag(1)O4 tetrahedra, corners with three equivalent Zn(1)O4 tetrahedra, edges with two equivalent Zn(2)O6 octahedra, and edges with four equivalent Ag(2)O6 octahedra. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one O(3) and three equivalent O(4) atoms to form ZnO4 tetrahedra that share corners with three equivalent Zn(2)O6 octahedra and corners with nine equivalent Ag(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 53-59°. In the second Zn site, Zn(2) is bonded to three equivalent O(1) and three equivalent O(4) atoms to form ZnO6 octahedra that share corners with three equivalent Ag(1)O4 tetrahedra, corners with three equivalent Zn(1)O4 tetrahedra, and edges with six equivalent Ag(2)O6 octahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Ag(1), two equivalent Ag(2), and one Zn(2) atom to form a mixture of distorted corner and edge-sharing OZnAg3 tetrahedra. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to one Ag(1) and three equivalent Ag(2) atoms. In the third O site, O(3) is bonded in a rectangular see-saw-like geometry to three equivalent Ag(2) and one Zn(1) atom. In the fourth O site, O(4) is bonded in a rectangular see-saw-like geometry to two equivalent Ag(2), one Zn(1), and one Zn(2) atom. is represented by the CIF file [CIF]
