The material structure described by MgZn2(AgO2)4 crystallizes in the triclinic P-1 space group. Mg(1) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form distorted edge-sharing MgO6 octahedra. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a rectangular see-saw-like geometry to one O(1), one O(2), and two equivalent O(3) atoms. In the second Ag site, Ag(2) is bonded in a rectangular see-saw-like geometry to two equivalent O(1) and two equivalent O(4) atoms. Zn(1) is bonded in a rectangular see-saw-like geometry to one O(2), one O(3), and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Ag(1) and two equivalent Ag(2) atoms. In the second O site, O(2) is bonded to two equivalent Mg(1), one Ag(1), and one Zn(1) atom to form OMg2ZnAg trigonal pyramids that share corners with two equivalent O(4)Zn2Ag2 tetrahedra, corners with four equivalent O(2)Mg2ZnAg trigonal pyramids, and  an edgeedge with one O(2)Mg2ZnAg trigonal pyramid. In the third O site, O(3) is bonded in a distorted see-saw-like geometry to one Mg(1), two equivalent Ag(1), and one Zn(1) atom. In the fourth O site, O(4) is bonded to two equivalent Ag(2) and two equivalent Zn(1) atoms to form OZn2Ag2 tetrahedra that share corners with two equivalent O(4)Zn2Ag2 tetrahedra, corners with two equivalent O(2)Mg2ZnAg trigonal pyramids, and  an edgeedge with one O(4)Zn2Ag2 tetrahedra. is represented by the CIF card [CIF]
