The material structure described by Dy2S2O crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 7-coordinate geometry to two equivalent S(2), four equivalent S(1), and one O(1) atom. In the second Dy site, Dy(2) is bonded in a 3-coordinate geometry to one S(1), three equivalent S(2), and three equivalent O(1) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded to one Dy(2) and four equivalent Dy(1) atoms to form distorted SDy5 trigonal bipyramids that share corners with three equivalent O(1)Dy4 tetrahedra, corners with four equivalent S(1)Dy5 trigonal bipyramids, edges with two equivalent O(1)Dy4 tetrahedra, and edges with four equivalent S(1)Dy5 trigonal bipyramids. In the second S site, S(2) is bonded in a 5-coordinate geometry to two equivalent Dy(1) and three equivalent Dy(2) atoms. O(1) is bonded to one Dy(1) and three equivalent Dy(2) atoms to form ODy4 tetrahedra that share corners with four equivalent O(1)Dy4 tetrahedra, corners with three equivalent S(1)Dy5 trigonal bipyramids,  an edgeedge with one O(1)Dy4 tetrahedra, and edges with two equivalent S(1)Dy5 trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
