The structure described by MgDyMnS4 is Spinel-derived structured and crystallizes in the orthorhombic Imma space group. Mg(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form MgS4 tetrahedra that share corners with six equivalent Dy(1)S6 octahedra and corners with six equivalent Mn(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 51-65°. Dy(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form DyS6 octahedra that share corners with six equivalent Mg(1)S4 tetrahedra, edges with two equivalent Dy(1)S6 octahedra, and edges with four equivalent Mn(1)S6 octahedra. Mn(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form MnS6 octahedra that share corners with six equivalent Mg(1)S4 tetrahedra, edges with two equivalent Mn(1)S6 octahedra, and edges with four equivalent Dy(1)S6 octahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to one Mg(1), one Dy(1), and two equivalent Mn(1) atoms. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to one Mg(1), two equivalent Dy(1), and one Mn(1) atom. is represented by the CIF card [CIF]
