The structure described by BeGd3CrS7 crystallizes in the hexagonal P6_3 space group. Be(1) is bonded in a tetrahedral geometry to one S(3) and three equivalent S(2) atoms. Gd(1) is bonded in a 8-coordinate geometry to one S(3), three equivalent S(2), and four equivalent S(1) atoms. Cr(1) is bonded to six equivalent S(1) atoms to form face-sharing CrS6 octahedra. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 6-coordinate geometry to four equivalent Gd(1) and two equivalent Cr(1) atoms. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to one Be(1) and three equivalent Gd(1) atoms. In the third S site, S(3) is bonded in a distorted tetrahedral geometry to one Be(1) and three equivalent Gd(1) atoms. is represented by the CIF file [CIF]
