The material structure described by MgWO5 crystallizes in the triclinic P-1 space group. Mg(1) is bonded to one O(1), one O(3), one O(4), one O(5), and two equivalent O(2) atoms to form MgO6 octahedra that share corners with five 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(5) atom to form WO4 tetrahedra that share corners with five equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 17-59°. There are five 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 distorted trigonal planar geometry to two equivalent Mg(1) and one W(1) atom. In the third O site, O(3) is bonded in a linear geometry to one Mg(1) and one W(1) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to one Mg(1) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one Mg(1) and one W(1) atom. is represented by the CIF file [CIF]
