The material structure described by Mg2Ag2O5 is Aluminum carbonitride-like structured and crystallizes in the orthorhombic Pbam space group. Mg(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Ag(1) is bonded to one O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted corner-sharing AgO5 square pyramids. There are three inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Mg(1) and two equivalent Ag(1) atoms to form distorted OMg4Ag2 octahedra that share corners with eight equivalent O(2)Mg2Ag2 tetrahedra, edges with two equivalent O(1)Mg4Ag2 octahedra, edges with two equivalent O(2)Mg2Ag2 tetrahedra, and faces with four equivalent O(3)Mg2Ag2 trigonal pyramids. In the second O site, O(2) is bonded to two equivalent Mg(1) and two equivalent Ag(1) atoms to form OMg2Ag2 tetrahedra that share corners with four equivalent O(1)Mg4Ag2 octahedra, corners with four equivalent O(2)Mg2Ag2 tetrahedra, corners with eight equivalent O(3)Mg2Ag2 trigonal pyramids, and  an edgeedge with one O(1)Mg4Ag2 octahedra. The corner-sharing octahedral tilt angles range from 14-57°. In the third O site, O(3) is bonded to two equivalent Mg(1) and two equivalent Ag(1) atoms to form distorted OMg2Ag2 trigonal pyramids that share corners with eight equivalent O(2)Mg2Ag2 tetrahedra, corners with two equivalent O(3)Mg2Ag2 trigonal pyramids,  an edgeedge with one O(3)Mg2Ag2 trigonal pyramid, and faces with two equivalent O(1)Mg4Ag2 octahedra. is represented by the CIF file [CIF]
