MgWO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Mg(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form distorted MgO4 trigonal pyramids that share corners with eight equivalent W(1)O6 octahedra and corners with two equivalent Mg(1)O4 trigonal pyramids. The corner-sharing octahedral tilt angles range from 62-82°. W(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent W(1)O6 octahedra and corners with eight equivalent Mg(1)O4 trigonal pyramids. The corner-sharing octahedral tilt angles are 47°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Mg(1) and two equivalent W(1) atoms. In the second O site, O(2) is bonded to two equivalent Mg(1) and two equivalent W(1) atoms to form distorted corner-sharing OMg2W2 tetrahedra.

The corner-sharing octahedral tilt angles range from 62-82°. Both Mg(1)-O(1) bond lengths are 2.04 Å. There is one shorter (2.04 Å) and one longer (2.11 Å) Mg(1)-O(2) bond length. W(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent W(1)O6 octahedra and corners with eight equivalent Mg(1)O4 trigonal pyramids. The corner-sharing octahedral tilt angles are 47°. Both W(1)-O(2) bond lengths are 2.15 Å. There are two shorter (2.04 Å) and two longer (2.09 Å) W(1)-O(1) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Mg(1) and two equivalent W(1) atoms. In the second O site, O(2) is bonded to two equivalent Mg(1) and two equivalent W(1) atoms to form distorted corner-sharing OMg2W2 tetrahedra.
