The material described by Mg2W3O8 is beta indium sulfide-derived structured and crystallizes in the monoclinic C2/m space group. Mg(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), and four equivalent O(3) atoms. There are two inequivalent W sites. In the first W site, W(1) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form edge-sharing WO6 octahedra. In the second W site, W(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form edge-sharing WO6 octahedra. There are three 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(2) atoms. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to one Mg(1), one W(1), and two equivalent W(2) atoms. In the third O site, O(3) is bonded to two equivalent Mg(1), one W(1), and one W(2) atom to form a mixture of distorted corner and edge-sharing OMg2W2 tetrahedra. is represented by the CIF card [CIF]
