The structure described by MgVSnO4 crystallizes in the triclinic P1 space group. Mg(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form distorted MgO4 tetrahedra that share corners with four equivalent V(1)O6 octahedra, corners with two equivalent Mg(1)O4 tetrahedra, and  an edgeedge with one V(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 4-54°. V(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form VO6 octahedra that share corners with four equivalent Mg(1)O4 tetrahedra, edges with two equivalent V(1)O6 octahedra, and  an edgeedge with one Mg(1)O4 tetrahedra. Sn(1) is bonded in a 5-coordinate geometry to one O(4), two equivalent O(1), and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to one Mg(1), 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 two equivalent Mg(1) and two equivalent V(1) atoms. In the third O site, O(3) is bonded in a rectangular see-saw-like geometry to one Mg(1), one V(1), and two equivalent Sn(1) atoms. In the fourth O site, O(4) is bonded in a trigonal planar geometry to two equivalent V(1) and one Sn(1) atom. is represented by the CIF card [CIF]
