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.
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. The Mg(1)-O(2) bond length is 2.19 Å. All Mg(1)-O(1) bond lengths are 2.19 Å. 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 is one shorter (1.96 Å) and one longer (2.24 Å) W(1)-O(2) bond length. There are two shorter (2.07 Å) and two longer (2.08 Å) W(1)-O(1) bond lengths. 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.
