The material described by MgVAg3O4 crystallizes in the monoclinic Cm space group. Mg(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form distorted MgO4 tetrahedra that share corners with two equivalent V(1)O4 tetrahedra and  an edgeedge with one V(1)O4 tetrahedra. V(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form distorted VO4 tetrahedra that share corners with two equivalent Mg(1)O4 tetrahedra and  an edgeedge with one Mg(1)O4 tetrahedra. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a linear geometry to two equivalent O(1) atoms. In the second Ag site, Ag(2) is bonded in a bent 120 degrees geometry to one O(2) and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Mg(1), one V(1), and two equivalent Ag(1) atoms to form a mixture of corner and edge-sharing OMgVAg2 tetrahedra. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Mg(1), one V(1), and one Ag(2) atom. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one Mg(1), one V(1), and one Ag(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
