Pr3MnAlS7 crystallizes in the hexagonal P6_3 space group. Pr(1) is bonded in a 7-coordinate geometry to one S(1), three equivalent S(2), and three equivalent S(3) atoms. Mn(1) is bonded to six equivalent S(2) atoms to form face-sharing MnS6 octahedra. Al(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 distorted tetrahedral geometry to three equivalent Pr(1) and one Al(1) atom. In the second S site, S(2) is bonded in a 5-coordinate geometry to three equivalent Pr(1) and two equivalent Mn(1) atoms. In the third S site, S(3) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Pr(1) and one Al(1) atom.
