The compound described by Mg(AgO2)2 crystallizes in the triclinic P-1 space group. Mg(1) is bonded to one O(1), two equivalent O(3), and two equivalent O(4) atoms to form edge-sharing MgO5 square pyramids. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 5-coordinate geometry to one O(2), two equivalent O(1), and two equivalent O(3) atoms. In the second Ag site, Ag(2) is bonded in a distorted square co-planar geometry to one O(1), one O(2), and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), one Ag(2), and two equivalent Ag(1) atoms. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Ag(1) and one Ag(2) atom. In the third O site, O(3) is bonded to two equivalent Mg(1) and two equivalent Ag(1) atoms to form a mixture of edge and corner-sharing OMg2Ag2 trigonal pyramids. In the fourth O site, O(4) is bonded to two equivalent Mg(1) and two equivalent Ag(2) atoms to form a mixture of edge and corner-sharing OMg2Ag2 tetrahedra. is represented by the CIF file [CIF]
