The structure described by MgDy2S4 crystallizes in the orthorhombic Pnma space group. Mg(1) is bonded in a trigonal pyramidal geometry to one S(2), one S(3), and two equivalent S(1) atoms. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 7-coordinate geometry to one S(2), two equivalent S(3), and four equivalent S(1) atoms. In the second Dy site, Dy(2) is bonded in a 6-coordinate geometry to one S(2), one S(3), and four equivalent S(1) atoms. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to one Mg(1), two equivalent Dy(1), and two equivalent Dy(2) atoms. In the second S site, S(2) is bonded in a T-shaped geometry to one Mg(1), one Dy(1), and one Dy(2) atom. In the third S site, S(3) is bonded in a rectangular see-saw-like geometry to one Mg(1), one Dy(2), and two equivalent Dy(1) atoms. is represented by the CIF card [CIF]
