MgVSnO4 crystallizes in the monoclinic P2/m space group. Mg(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MgO6 octahedra that share corners with four equivalent V(1)O6 octahedra, edges with two equivalent Mg(1)O6 octahedra, edges with four equivalent Sn(1)O6 octahedra, and faces with two equivalent V(1)O6 octahedra. The corner-sharing octahedral tilt angles are 43°. V(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form VO6 octahedra that share corners with four equivalent Mg(1)O6 octahedra, corners with eight equivalent Sn(1)O6 octahedra, edges with two equivalent V(1)O6 octahedra, and faces with two equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-51°. Sn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form SnO6 octahedra that share corners with eight equivalent V(1)O6 octahedra, edges with two equivalent Sn(1)O6 octahedra, and edges with four equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 48-51°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted 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 to two equivalent Mg(1), two equivalent V(1), and one Sn(1) atom to form a mixture of distorted edge and corner-sharing OMg2V2Sn square pyramids.
