The structure described by BeLa3AlS7 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. La(1) is bonded in a 8-coordinate geometry to one S(3), three equivalent S(2), and four equivalent S(1) atoms. Al(1) is bonded to six equivalent S(1) atoms to form face-sharing AlS6 octahedra. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 6-coordinate geometry to four equivalent La(1) and two equivalent Al(1) atoms. In the second S site, S(2) is bonded in a distorted rectangular see-saw-like geometry to one Be(1) and three equivalent La(1) atoms. In the third S site, S(3) is bonded in a distorted tetrahedral geometry to one Be(1) and three equivalent La(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
