Dy3MnAlS7 crystallizes in the hexagonal P6_3 space group. Dy(1) is bonded in a 7-coordinate geometry to one S(3), three equivalent S(1), and three equivalent S(2) atoms. Mn(1) is bonded to six equivalent S(1) atoms to form face-sharing MnS6 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 to three equivalent Dy(1) and two equivalent Mn(1) atoms to form distorted SDy3Mn2 square pyramids that share corners with two equivalent S(1)Dy3Mn2 square pyramids, corners with three equivalent S(3)Dy3Al tetrahedra, edges with four equivalent S(1)Dy3Mn2 square pyramids, and faces with two equivalent S(1)Dy3Mn2 square pyramids. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to three equivalent Dy(1) and one Al(1) atom. In the third S site, S(3) is bonded to three equivalent Dy(1) and one Al(1) atom to form distorted corner-sharing SDy3Al tetrahedra.
Dy3MnAlS7 crystallizes in the hexagonal P6_3 space group. Dy(1) is bonded in a 7-coordinate geometry to one S(3), three equivalent S(1), and three equivalent S(2) atoms. The Dy(1)-S(3) bond length is 2.75 Å. There are a spread of Dy(1)-S(1) bond distances ranging from 2.72-2.84 Å. There are a spread of Dy(1)-S(2) bond distances ranging from 2.79-2.94 Å.
