The crystal structure described by Dy4Te3S4 crystallizes in the monoclinic C2/m space group. Dy(1) is bonded to one Te(2), two equivalent Te(1), two equivalent S(1), and two equivalent S(2) atoms to form a mixture of distorted face, corner, and edge-sharing DyTe3S4 pentagonal bipyramids. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 5-coordinate geometry to four equivalent Dy(1) and one Te(1) atom. In the second Te site, Te(2) is bonded in a square co-planar geometry to four equivalent Dy(1) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded to four equivalent Dy(1) atoms to form a mixture of corner and edge-sharing SDy4 trigonal pyramids. In the second S site, S(2) is bonded to four equivalent Dy(1) atoms to form a mixture of corner and edge-sharing SDy4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
