The structure described by MgWO6 crystallizes in the monoclinic P2_1/c space group. Mg(1) is bonded to one O(1), one O(2), one O(5), one O(6), and two equivalent O(4) atoms to form distorted MgO6 octahedra that share corners with four equivalent W(1)O4 tetrahedra and  an edgeedge with one Mg(1)O6 octahedra. W(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form WO4 tetrahedra that share corners with four equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 9-56°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Mg(1) and one W(1) atom. In the second O site, O(2) is bonded in a linear geometry to one Mg(1) and one W(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one W(1) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to two equivalent Mg(1) and one W(1) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one Mg(1) and one O(6) atom. In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to one Mg(1) and one O(5) atom. is represented by the Crystallographic Information File (CIF) [CIF]
