The structure described by Dy5S7 crystallizes in the monoclinic C2/m space group. There are three inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to two equivalent S(3) and four equivalent S(2) atoms to form DyS6 octahedra that share corners with two equivalent Dy(2)S6 octahedra, corners with four equivalent Dy(3)S7 pentagonal bipyramids, edges with two equivalent Dy(1)S6 octahedra, and edges with six equivalent Dy(3)S7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 56°. In the second Dy site, Dy(2) is bonded to one S(3), two equivalent S(1), and three equivalent S(4) atoms to form DyS6 octahedra that share  a cornercorner with one Dy(1)S6 octahedra, corners with two equivalent Dy(2)S6 octahedra, corners with six equivalent Dy(3)S7 pentagonal bipyramids, edges with five equivalent Dy(2)S6 octahedra, and  an edgeedge with one Dy(3)S7 pentagonal bipyramid. The corner-sharing octahedral tilt angles range from 0-56°. In the third Dy site, Dy(3) is bonded to two equivalent S(3), two equivalent S(4), and three equivalent S(2) atoms to form distorted DyS7 pentagonal bipyramids that share corners with two equivalent Dy(1)S6 octahedra, corners with six equivalent Dy(2)S6 octahedra,  an edgeedge with one Dy(2)S6 octahedra, edges with three equivalent Dy(1)S6 octahedra, edges with two equivalent Dy(3)S7 pentagonal bipyramids, and faces with two equivalent Dy(3)S7 pentagonal bipyramids. The corner-sharing octahedral tilt angles range from 22-68°. There are four inequivalent S sites. In the first S site, S(1) is bonded in a square co-planar geometry to four equivalent Dy(2) atoms. In the second S site, S(2) is bonded to two equivalent Dy(1) and three equivalent Dy(3) atoms to form distorted SDy5 trigonal bipyramids that share corners with four equivalent S(3)Dy4 tetrahedra, corners with two equivalent S(2)Dy5 trigonal bipyramids, corners with four equivalent S(4)Dy5 trigonal bipyramids, edges with three equivalent S(3)Dy4 tetrahedra,  an edgeedge with one S(4)Dy5 trigonal bipyramid, and edges with five equivalent S(2)Dy5 trigonal bipyramids. In the third S site, S(3) is bonded to one Dy(1), one Dy(2), and two equivalent Dy(3) atoms to form distorted SDy4 tetrahedra that share corners with three equivalent S(3)Dy4 tetrahedra, corners with four equivalent S(2)Dy5 trigonal bipyramids, corners with five equivalent S(4)Dy5 trigonal bipyramids,  an edgeedge with one S(4)Dy5 trigonal bipyramid, and edges with three equivalent S(2)Dy5 trigonal bipyramids. In the fourth S site, S(4) is bonded to two equivalent Dy(3) and three equivalent Dy(2) atoms to form SDy5 trigonal bipyramids that share corners with five equivalent S(3)Dy4 tetrahedra, corners with four equivalent S(2)Dy5 trigonal bipyramids,  an edgeedge with one S(3)Dy4 tetrahedra,  an edgeedge with one S(2)Dy5 trigonal bipyramid, and edges with four equivalent S(4)Dy5 trigonal bipyramids. is represented by the CIF file [CIF]
