Nd3CoAlS7 crystallizes in the hexagonal P6_3 space group. Nd(1) is bonded in a 7-coordinate geometry to one S(3), three equivalent S(2), and four equivalent S(1) atoms. Co(1) is bonded to six equivalent S(1) atoms to form face-sharing CoS6 octahedra. Al(1) is bonded in a tetrahedral geometry to one S(3) and three equivalent S(2) atoms. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 6-coordinate geometry to four equivalent Nd(1) and two equivalent Co(1) atoms. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to three equivalent Nd(1) and one Al(1) atom. In the third S site, S(3) is bonded in a tetrahedral geometry to three equivalent Nd(1) and one Al(1) atom.
