NaGd3GeS7 crystallizes in the hexagonal P6_3 space group. Na(1) is bonded to six equivalent S(2) atoms to form face-sharing NaS6 octahedra. Gd(1) is bonded in a 8-coordinate geometry to one S(1), three equivalent S(3), and four equivalent S(2) atoms. Ge(1) is bonded in a tetrahedral geometry to one S(1) and three equivalent S(3) atoms. There are three inequivalent S sites. In the first S site, S(1) is bonded in a tetrahedral geometry to three equivalent Gd(1) and one Ge(1) atom. In the second S site, S(2) is bonded in a 6-coordinate geometry to two equivalent Na(1) and four equivalent Gd(1) atoms. In the third S site, S(3) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Gd(1) and one Ge(1) atom.
