The crystal structure described by Mg2Dy3VS8 is Spinel-derived structured and crystallizes in the monoclinic C2/m space group. Mg(1) is bonded to one S(1), one S(3), and two equivalent S(2) atoms to form MgS4 tetrahedra that share corners with three equivalent Dy(1)S6 octahedra, corners with three equivalent V(1)S6 octahedra, and corners with six equivalent Dy(2)S6 octahedra. The corner-sharing octahedral tilt angles range from 50-60°. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to two equivalent S(3) and four equivalent S(2) atoms to form DyS6 octahedra that share corners with six equivalent Mg(1)S4 tetrahedra, edges with two equivalent V(1)S6 octahedra, and edges with four equivalent Dy(2)S6 octahedra. In the second Dy site, Dy(2) is bonded to two equivalent S(1), two equivalent S(2), and two equivalent S(3) atoms to form DyS6 octahedra that share corners with six equivalent Mg(1)S4 tetrahedra, edges with two equivalent Dy(1)S6 octahedra, edges with two equivalent Dy(2)S6 octahedra, and edges with two equivalent V(1)S6 octahedra. V(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form VS6 octahedra that share corners with six equivalent Mg(1)S4 tetrahedra, edges with two equivalent Dy(1)S6 octahedra, and edges with four equivalent Dy(2)S6 octahedra. There are three inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to one Mg(1), two equivalent Dy(2), and one V(1) atom. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to one Mg(1), one Dy(1), one Dy(2), and one V(1) atom. In the third S site, S(3) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), one Dy(1), and two equivalent Dy(2) atoms. is represented by the CIF card [CIF]
