The compound described by MgV4SnO12 crystallizes in the monoclinic C2 space group. Mg(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(4), and two equivalent O(6) atoms. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(1), one O(2), one O(4), and one O(5) atom to form VO4 tetrahedra that share  a cornercorner with one Sn(1)O6 octahedra and corners with two equivalent V(2)O4 tetrahedra. The corner-sharing octahedral tilt angles are 51°. In the second V site, V(2) is bonded to one O(3), one O(4), one O(5), and one O(6) atom to form VO4 tetrahedra that share corners with two equivalent Sn(1)O6 octahedra and corners with two equivalent V(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 37-49°. Sn(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(6) atoms to form SnO6 octahedra that share corners with two equivalent V(1)O4 tetrahedra and corners with four equivalent V(2)O4 tetrahedra. There are six inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Mg(1), one V(1), and one Sn(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one V(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one V(2) and one Sn(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Mg(1), one V(1), and one V(2) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one V(1) and one V(2) atom. In the sixth O site, O(6) is bonded in a distorted T-shaped geometry to one Mg(1), one V(2), and one Sn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
