The structure described by Mg2DyV3S8 is Spinel-derived structured and crystallizes in the monoclinic C2/m space group. Mg(1) is bonded to one S(1), one S(2), and two equivalent S(3) 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 V(2)S6 octahedra. The corner-sharing octahedral tilt angles range from 54-66°. Dy(1) is bonded to two equivalent S(2) and four equivalent S(3) 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 V(2)S6 octahedra. There are two inequivalent V sites. In the first V site, V(1) is bonded to two equivalent S(1) and four equivalent S(3) 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 V(2)S6 octahedra. In the second V site, V(2) is bonded to two equivalent S(1), two equivalent S(2), and two equivalent S(3) atoms to form VS6 octahedra that share corners with six equivalent Mg(1)S4 tetrahedra, edges with two equivalent Dy(1)S6 octahedra, edges with two equivalent V(1)S6 octahedra, and edges with two equivalent V(2)S6 octahedra. There are three inequivalent S sites. In the first S site, S(1) is bonded to one Mg(1), one V(1), and two equivalent V(2) atoms to form distorted corner-sharing SMgV3 trigonal pyramids. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to one Mg(1), one Dy(1), and two equivalent V(2) atoms. In the third S site, S(3) is bonded in a rectangular see-saw-like geometry to one Mg(1), one Dy(1), one V(1), and one V(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
