The compound described by MgZn(CoS2)4 crystallizes in the monoclinic Cm space group. Mg(1) is bonded in a distorted rectangular see-saw-like geometry to one S(5), one S(6), and two equivalent S(1) atoms. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded to one S(1), one S(2), one S(3), one S(4), one S(5), and one S(6) atom to form CoS6 octahedra that share edges with two equivalent Co(1)S6 octahedra, edges with two equivalent Co(2)S6 octahedra, edges with two equivalent Co(3)S6 octahedra, and edges with two equivalent Zn(1)S6 octahedra. In the second Co site, Co(2) is bonded to one S(4), one S(5), two equivalent S(1), and two equivalent S(2) atoms to form CoS6 octahedra that share edges with two equivalent Co(3)S6 octahedra, edges with two equivalent Zn(1)S6 octahedra, and edges with four equivalent Co(1)S6 octahedra. In the third Co site, Co(3) is bonded to one S(3), one S(6), two equivalent S(1), and two equivalent S(2) atoms to form distorted CoS6 octahedra that share corners with six equivalent Zn(1)S6 octahedra, edges with two equivalent Co(2)S6 octahedra, and edges with four equivalent Co(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 10-19°. Zn(1) is bonded to one S(3), one S(6), two equivalent S(1), and two equivalent S(2) atoms to form distorted ZnS6 octahedra that share corners with six equivalent Co(3)S6 octahedra, edges with two equivalent Co(2)S6 octahedra, and edges with four equivalent Co(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 10-19°. There are six inequivalent S sites. In the first S site, S(1) is bonded to one Mg(1), one Co(1), one Co(2), one Co(3), and one Zn(1) atom to form SMgZnCo3 trigonal bipyramids that share  a cornercorner with one S(5)MgCo3 tetrahedra,  an edgeedge with one S(5)MgCo3 tetrahedra, edges with two equivalent S(1)MgZnCo3 trigonal bipyramids, and edges with two equivalent S(6)MgZnCo3 trigonal bipyramids. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to one Co(1), one Co(2), one Co(3), and one Zn(1) atom. In the third S site, S(3) is bonded in a distorted rectangular see-saw-like geometry to one Co(3), two equivalent Co(1), and one Zn(1) atom. In the fourth S site, S(4) is bonded in a distorted T-shaped geometry to one Co(2) and two equivalent Co(1) atoms. In the fifth S site, S(5) is bonded to one Mg(1), one Co(2), and two equivalent Co(1) atoms to form a mixture of distorted corner and edge-sharing SMgCo3 tetrahedra. In the sixth S site, S(6) is bonded to one Mg(1), one Co(3), two equivalent Co(1), and one Zn(1) atom to form SMgZnCo3 trigonal bipyramids that share  a cornercorner with one S(5)MgCo3 tetrahedra,  an edgeedge with one S(5)MgCo3 tetrahedra, and edges with four equivalent S(1)MgZnCo3 trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
