The material described by MgMn2(AgO3)2 crystallizes in the triclinic P1 space group. Mg(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), one O(5), and one O(6) atom. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form a mixture of edge and corner-sharing MnO6 octahedra. In the second Mn site, Mn(2) is bonded to one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form a mixture of edge and corner-sharing MnO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 46°. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 4-coordinate geometry to one O(1), one O(3), one O(4), and one O(6) atom. In the second Ag site, Ag(2) is bonded in a 2-coordinate geometry to one O(1) and one O(2) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded to one Mg(1), one Mn(1), one Ag(1), and one Ag(2) atom to form a mixture of distorted edge and corner-sharing OMgMnAg2 tetrahedra. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to one Mg(1), one Mn(1), one Mn(2), and one Ag(2) atom. In the third O site, O(3) is bonded to one Mg(1), one Mn(1), one Mn(2), and one Ag(1) atom to form distorted OMgMn2Ag trigonal pyramids that share  a cornercorner with one O(1)MgMnAg2 tetrahedra, corners with two equivalent O(6)MgMn2Ag trigonal pyramids,  an edgeedge with one O(1)MgMnAg2 tetrahedra, and  an edgeedge with one O(6)MgMn2Ag trigonal pyramid. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Mn(1), one Mn(2), and one Ag(1) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one Mg(1), one Mn(1), and one Mn(2) atom. In the sixth O site, O(6) is bonded to one Mg(1), one Mn(1), one Mn(2), and one Ag(1) atom to form distorted OMgMn2Ag trigonal pyramids that share corners with three equivalent O(1)MgMnAg2 tetrahedra, corners with two equivalent O(3)MgMn2Ag trigonal pyramids, and  an edgeedge with one O(3)MgMn2Ag trigonal pyramid. is represented by the CIF file [CIF]
