The structure described by Dy3CuSnS7 crystallizes in the hexagonal P6_3 space group. Dy(1) is bonded in a 7-coordinate geometry to one S(1), three equivalent S(2), and three equivalent S(3) atoms. Cu(1) is bonded in a trigonal planar geometry to three equivalent S(3) atoms. Sn(1) is bonded in a tetrahedral geometry to one S(1) and three equivalent S(2) atoms. There are three inequivalent S sites. In the first S site, S(1) is bonded in a tetrahedral geometry to three equivalent Dy(1) and one Sn(1) atom. In the second S site, S(2) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Dy(1) and one Sn(1) atom. In the third S site, S(3) is bonded in a 4-coordinate geometry to three equivalent Dy(1) and one Cu(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
