The compound described by Ho3CuGeS7 crystallizes in the hexagonal P6_3 space group. Ho(1) is bonded in a 9-coordinate geometry to one Cu(1), one S(2), three equivalent S(3), and four equivalent S(1) atoms. Cu(1) is bonded in a trigonal planar geometry to three equivalent Ho(1) and three equivalent S(1) atoms. Ge(1) is bonded in a tetrahedral geometry to one S(2) and three equivalent S(3) atoms. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to four equivalent Ho(1) and one Cu(1) atom. In the second S site, S(2) is bonded in a tetrahedral geometry to three equivalent Ho(1) and one Ge(1) atom. In the third S site, S(3) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Ho(1) and one Ge(1) atom. is represented by the CIF file [CIF]
