The material structure described by Ho3CuSnS7 crystallizes in the hexagonal P6_3 space group. Ho(1) is bonded in a 7-coordinate geometry to one S(3), three equivalent S(1), and three equivalent S(2) atoms. Cu(1) is bonded in a trigonal planar geometry to three equivalent S(2) atoms. Sn(1) is bonded in a tetrahedral geometry to one S(3) and three equivalent S(1) atoms. There are three inequivalent S sites. In the first S site, S(1) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Ho(1) and one Sn(1) atom. In the second S site, S(2) is bonded in a 4-coordinate geometry to three equivalent Ho(1) and one Cu(1) atom. In the third S site, S(3) is bonded in a tetrahedral geometry to three equivalent Ho(1) and one Sn(1) atom. is represented by the CIF card [CIF]
