The compound described by Gd2WO6 crystallizes in the monoclinic C2/c space group. There are three inequivalent Gd sites. In the first Gd site, Gd(1) is bonded in a distorted body-centered cubic geometry to two equivalent O(4), two equivalent O(5), and four equivalent O(6) atoms. In the second Gd site, Gd(2) is bonded in a distorted body-centered cubic geometry to two equivalent O(4), two equivalent O(5), and four equivalent O(2) atoms. In the third Gd site, Gd(3) is bonded in a 8-coordinate geometry to one O(4), one O(5), two equivalent O(1), two equivalent O(3), and two equivalent O(6) atoms. W(1) is bonded in a distorted trigonal bipyramidal geometry to one O(1), one O(2), one O(3), one O(4), and one O(5) atom. There are six inequivalent O sites. In the first O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Gd(3) and one W(1) atom. In the second O site, O(4) is bonded in a 4-coordinate geometry to one Gd(1), one Gd(2), one Gd(3), and one W(1) atom. In the third O site, O(5) is bonded to one Gd(1), one Gd(2), one Gd(3), and one W(1) atom to form OGd3W tetrahedra that share corners with two equivalent O(5)Gd3W tetrahedra, corners with four equivalent O(6)Gd4 tetrahedra, and  an edgeedge with one O(6)Gd4 tetrahedra. In the fourth O site, O(6) is bonded to two equivalent Gd(1) and two equivalent Gd(3) atoms to form OGd4 tetrahedra that share corners with two equivalent O(6)Gd4 tetrahedra, corners with four equivalent O(5)Gd3W tetrahedra,  an edgeedge with one O(5)Gd3W tetrahedra, and edges with three equivalent O(6)Gd4 tetrahedra. In the fifth O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Gd(3) and one W(1) atom. In the sixth O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Gd(2) and one W(1) atom. is represented by the CIF file [CIF]
