MgWO4 crystallizes in the monoclinic P2/c space group. Mg(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form MgO6 octahedra that share corners with four equivalent W(1)O6 octahedra, edges with two equivalent Mg(1)O6 octahedra, and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 22-28°. W(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form distorted WO6 octahedra that share corners with four equivalent Mg(1)O6 octahedra, edges with two equivalent Mg(1)O6 octahedra, and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 22-28°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a T-shaped geometry to two equivalent Mg(1) and one W(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Mg(1) and two equivalent W(1) atoms.

The corner-sharing octahedral tilt angles range from 22-28°. Both Mg(1)-O(2) bond lengths are 2.09 Å. There are two shorter (2.06 Å) and two longer (2.12 Å) Mg(1)-O(1) bond lengths. W(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form distorted WO6 octahedra that share corners with four equivalent Mg(1)O6 octahedra, edges with two equivalent Mg(1)O6 octahedra, and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 22-28°. Both W(1)-O(1) bond lengths are 1.85 Å. There are two shorter (2.02 Å) and two longer (2.03 Å) W(1)-O(2) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a T-shaped geometry to two equivalent Mg(1) and one W(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Mg(1) and two equivalent W(1) atoms.
