The structure described by Dy2SnS5 crystallizes in the orthorhombic Pbam space group. Dy(1) is bonded in a 8-coordinate geometry to two equivalent S(1), two equivalent S(3), and four equivalent S(2) atoms. Sn(1) is bonded to two equivalent S(2) and four equivalent S(3) atoms to form edge-sharing SnS6 octahedra. There are three inequivalent S sites. In the first S site, S(1) is bonded in a square co-planar geometry to four equivalent Dy(1) atoms. In the second S site, S(2) is bonded to four equivalent Dy(1) and one Sn(1) atom to form distorted SDy4Sn trigonal bipyramids that share corners with five equivalent S(2)Dy4Sn trigonal bipyramids, corners with four equivalent S(3)Dy2Sn2 trigonal pyramids, edges with four equivalent S(2)Dy4Sn trigonal bipyramids, and edges with four equivalent S(3)Dy2Sn2 trigonal pyramids. In the third S site, S(3) is bonded to two equivalent Dy(1) and two equivalent Sn(1) atoms to form distorted SDy2Sn2 trigonal pyramids that share corners with four equivalent S(2)Dy4Sn trigonal bipyramids, corners with six equivalent S(3)Dy2Sn2 trigonal pyramids, edges with four equivalent S(2)Dy4Sn trigonal bipyramids, and  an edgeedge with one S(3)Dy2Sn2 trigonal pyramid. is represented by the CIF file [CIF]
