The material described by Mg2WMnO6 crystallizes in the monoclinic C2 space group. Mg(1) is bonded to one O(3), two equivalent O(1), and two equivalent O(2) atoms to form distorted MgO5 trigonal bipyramids that share  a cornercorner with one W(1)O6 octahedra, corners with three equivalent Mn(1)O4 tetrahedra, corners with two equivalent Mg(1)O5 trigonal bipyramids, edges with two equivalent W(1)O6 octahedra, and  an edgeedge with one Mg(1)O5 trigonal bipyramid. The corner-sharing octahedral tilt angles are 51°. W(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form WO6 octahedra that share corners with four equivalent Mn(1)O4 tetrahedra, corners with two equivalent Mg(1)O5 trigonal bipyramids, and edges with four equivalent Mg(1)O5 trigonal bipyramids. Mn(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form distorted MnO4 tetrahedra that share corners with four equivalent W(1)O6 octahedra and corners with six equivalent Mg(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 44-48°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted see-saw-like geometry to two equivalent Mg(1), one W(1), and one Mn(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Mg(1) and one W(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Mg(1), one W(1), and one Mn(1) atom. is represented by the CIF card [CIF]
