Dy3CoGaS7 crystallizes in the hexagonal P6_3 space group. Dy(1) is bonded in a 7-coordinate geometry to one S(2), three equivalent S(1), and three equivalent S(3) atoms. Co(1) is bonded to six equivalent S(3) atoms to form face-sharing CoS6 octahedra. Ga(1) is bonded in a tetrahedral geometry to one S(2) and three equivalent S(1) atoms. There are three inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to three equivalent Dy(1) and one Ga(1) atom. In the second S site, S(2) is bonded to three equivalent Dy(1) and one Ga(1) atom to form corner-sharing SDy3Ga tetrahedra. In the third S site, S(3) is bonded to three equivalent Dy(1) and two equivalent Co(1) atoms to form SDy3Co2 square pyramids that share corners with two equivalent S(3)Dy3Co2 square pyramids, corners with three equivalent S(2)Dy3Ga tetrahedra, edges with four equivalent S(3)Dy3Co2 square pyramids, and faces with two equivalent S(3)Dy3Co2 square pyramids.
Dy3CoGaS7 crystallizes in the hexagonal P6_3 space group. Dy(1) is bonded in a 7-coordinate geometry to one S(2), three equivalent S(1), and three equivalent S(3) atoms. The Dy(1)-S(2) bond length is 2.75 Å. There are a spread of Dy(1)-S(1) bond distances ranging from 2.79-2.98 Å. There are a spread of Dy(1)-S(3) bond distances ranging from 2.73-2.80 Å. Co(1) is bonded to six equivalent S(3) atoms to form face-sharing CoS6 octahedra. There are three shorter (2.38 Å) and three longer (2.43 Å) Co(1)-S(3) bond lengths.
