The compound described by Ca(AgO2)2 is Spinel-like structured and crystallizes in the orthorhombic Imma 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 Ag(1)O4 tetrahedra, edges with two equivalent Ca(1)O6 octahedra, and edges with four equivalent Ag(2)O6 octahedra. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form AgO4 tetrahedra that share corners with six equivalent Ca(1)O6 octahedra and corners with six equivalent Ag(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 52-73°. 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)O4 tetrahedra, edges with two equivalent Ag(2)O6 octahedra, and edges with four equivalent Ca(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ca(1), one Ag(1), and one Ag(2) atom to form distorted OCa2Ag2 tetrahedra that share corners with six equivalent O(1)Ca2Ag2 tetrahedra, corners with six equivalent O(2)CaAg3 trigonal pyramids,  an edgeedge with one O(1)Ca2Ag2 tetrahedra, and edges with two equivalent O(2)CaAg3 trigonal pyramids. In the second O site, O(2) is bonded to one Ca(1), one Ag(1), and two equivalent Ag(2) atoms to form OCaAg3 trigonal pyramids that share corners with six equivalent O(1)Ca2Ag2 tetrahedra, corners with six equivalent O(2)CaAg3 trigonal pyramids, edges with two equivalent O(1)Ca2Ag2 tetrahedra, and  an edgeedge with one O(2)CaAg3 trigonal pyramid. is represented by the CIF file [CIF]
