The structure described by MgVSnO4 crystallizes in the monoclinic Pm space group. Mg(1) is bonded to one O(2), one O(4), and two equivalent O(3) atoms to form distorted MgO4 tetrahedra that share corners with four equivalent Sn(1)O6 octahedra, corners with two equivalent Mg(1)O4 tetrahedra, and  an edgeedge with one Sn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 7-57°. V(1) is bonded in a 5-coordinate geometry to one O(1), two equivalent O(2), and two equivalent O(4) atoms. Sn(1) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms to form SnO6 octahedra that share corners with four equivalent Mg(1)O4 tetrahedra, edges with two equivalent Sn(1)O6 octahedra, and  an edgeedge with one Mg(1)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one V(1) and two equivalent Sn(1) atoms. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Mg(1), two equivalent V(1), and one Sn(1) atom. In the third O site, O(3) is bonded in a square co-planar geometry to two equivalent Mg(1) and two equivalent Sn(1) atoms. In the fourth O site, O(4) is bonded in a rectangular see-saw-like geometry to one Mg(1), two equivalent V(1), and one Sn(1) atom. is represented by the CIF card [CIF]
