The crystal structure described by MgWO3 crystallizes in the monoclinic Cm space group. Mg(1) is bonded in a pentagonal planar geometry to one O(2) and four equivalent O(1) atoms. W(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 18°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a see-saw-like geometry to two equivalent Mg(1) and two equivalent W(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Mg(1) and two equivalent W(1) atoms. is represented by the CIF file [CIF]
