The structure described by BeLa3AlS7 crystallizes in the hexagonal P6_3 space group. Be(1) is bonded to six equivalent S(3) atoms to form face-sharing BeS6 octahedra. La(1) is bonded in a 8-coordinate geometry to one S(1), three equivalent S(2), and four equivalent S(3) atoms. Al(1) is bonded in a tetrahedral geometry to one S(1) and three equivalent S(2) atoms. There are three inequivalent S sites. In the first S site, S(1) is bonded in a tetrahedral geometry to three equivalent La(1) and one Al(1) atom. In the second S site, S(2) is bonded in a distorted rectangular see-saw-like geometry to three equivalent La(1) and one Al(1) atom. In the third S site, S(3) is bonded in a 6-coordinate geometry to two equivalent Be(1) and four equivalent La(1) atoms. is represented by the CIF card [CIF]
