The structure described by Eu2WO6 crystallizes in the monoclinic C2/c space group. There are three inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a distorted body-centered cubic geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(5) atoms. In the second Eu site, Eu(2) is bonded in a distorted body-centered cubic geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(6) atoms. In the third Eu site, Eu(3) is bonded in a 8-coordinate geometry to one O(1), one O(2), two equivalent O(3), two equivalent O(4), 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 distorted trigonal planar geometry to two equivalent Eu(3) and one W(1) atom. In the second O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Eu(3) and one W(1) atom. In the third O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Eu(1) and one W(1) atom. In the fourth O site, O(6) is bonded to two equivalent Eu(2) and two equivalent Eu(3) atoms to form OEu4 tetrahedra that share corners with two equivalent O(6)Eu4 tetrahedra, corners with four equivalent O(1)Eu3W tetrahedra,  an edgeedge with one O(1)Eu3W tetrahedra, and edges with three equivalent O(6)Eu4 tetrahedra. In the fifth O site, O(1) is bonded to one Eu(1), one Eu(2), one Eu(3), and one W(1) atom to form OEu3W tetrahedra that share corners with two equivalent O(1)Eu3W tetrahedra, corners with four equivalent O(6)Eu4 tetrahedra, and  an edgeedge with one O(6)Eu4 tetrahedra. In the sixth O site, O(2) is bonded in a 4-coordinate geometry to one Eu(1), one Eu(2), one Eu(3), and one W(1) atom. is represented by the CIF file [CIF]
