Ca(AgO2)2 crystallizes in the orthorhombic Pmmn space group. There are two inequivalent Ca sites. In the first Ca site, Ca(1) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form distorted edge-sharing CaO6 pentagonal pyramids. In the second Ca site, Ca(2) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form distorted edge-sharing CaO6 pentagonal pyramids. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a rectangular see-saw-like geometry to four equivalent O(3) atoms. In the second Ag site, Ag(2) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a trigonal non-coplanar geometry to one Ca(1) and two equivalent Ag(2) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Ca(2) and two equivalent Ag(2) atoms. In the third O site, O(3) is bonded in a distorted see-saw-like geometry to one Ca(1), one Ca(2), and two equivalent Ag(1) atoms.

In the first Ca site, Ca(1) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form distorted edge-sharing CaO6 pentagonal pyramids. Both Ca(1)-O(1) bond lengths are 2.31 Å. All Ca(1)-O(3) bond lengths are 2.50 Å. In the second Ca site, Ca(2) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form distorted edge-sharing CaO6 pentagonal pyramids. Both Ca(2)-O(2) bond lengths are 2.28 Å. All Ca(2)-O(3) bond lengths are 2.50 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a rectangular see-saw-like geometry to four equivalent O(3) atoms. There are two shorter (2.05 Å) and two longer (2.06 Å) Ag(1)-O(3) bond lengths. In the second Ag site, Ag(2) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. Both Ag(2)-O(1) bond lengths are 2.03 Å. Both Ag(2)-O(2) bond lengths are 2.02 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded in a trigonal non-coplanar geometry to one Ca(1) and two equivalent Ag(2) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Ca(2) and two equivalent Ag(2) atoms. In the third O site, O(3) is bonded in a distorted see-saw-like geometry to one Ca(1), one Ca(2), and two equivalent Ag(1) atoms.
