The structure described by Mg(MnS2)2 crystallizes in the monoclinic Pm space group. Mg(1) is bonded to one S(1), one S(2), and two equivalent S(4) atoms to form distorted MgS4 tetrahedra that share corners with three equivalent Mn(1)S5 square pyramids, corners with four equivalent Mn(2)S5 square pyramids, corners with two equivalent Mg(1)S4 tetrahedra, and  an edgeedge with one Mn(1)S5 square pyramid. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one S(1), two equivalent S(3), and two equivalent S(4) atoms to form MnS5 square pyramids that share corners with four equivalent Mn(2)S5 square pyramids, corners with three equivalent Mg(1)S4 tetrahedra, edges with two equivalent Mn(1)S5 square pyramids, and  an edgeedge with one Mg(1)S4 tetrahedra. In the second Mn site, Mn(2) is bonded to one S(3), two equivalent S(1), and two equivalent S(2) atoms to form distorted MnS5 square pyramids that share corners with four equivalent Mn(1)S5 square pyramids, corners with four equivalent Mg(1)S4 tetrahedra, and edges with two equivalent Mn(2)S5 square pyramids. There are four inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to one Mg(1), one Mn(1), and two equivalent Mn(2) atoms. In the second S site, S(2) is bonded in a trigonal non-coplanar geometry to one Mg(1) and two equivalent Mn(2) atoms. In the third S site, S(3) is bonded in a distorted trigonal planar geometry to one Mn(2) and two equivalent Mn(1) atoms. In the fourth S site, S(4) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Mg(1) and two equivalent Mn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
