MgZn2(CoS2)4 crystallizes in the orthorhombic Imm2 space group. Mg(1) is bonded in a body-centered cubic geometry to two equivalent Co(1), two equivalent Co(2), two equivalent S(2), and two equivalent S(3) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 7-coordinate geometry to one Mg(1), one S(1), one S(3), two equivalent S(2), and two equivalent S(4) atoms. In the second Co site, Co(2) is bonded in a 7-coordinate geometry to one Mg(1), one S(2), one S(4), two equivalent S(1), and two equivalent S(3) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a tetrahedral geometry to two equivalent S(1) and two equivalent S(4) atoms. In the second Zn site, Zn(2) is bonded in a tetrahedral geometry to two equivalent S(2) and two equivalent S(3) atoms. There are four inequivalent S sites. In the first S site, S(1) is bonded to one Co(1), two equivalent Co(2), and one Zn(1) atom to form a mixture of distorted corner and edge-sharing SZnCo3 trigonal pyramids. In the second S site, S(2) is bonded in a 5-coordinate geometry to one Mg(1), one Co(2), two equivalent Co(1), and one Zn(2) atom. In the third S site, S(3) is bonded in a 5-coordinate geometry to one Mg(1), one Co(1), two equivalent Co(2), and one Zn(2) atom. In the fourth S site, S(4) is bonded to one Co(2), two equivalent Co(1), and one Zn(1) atom to form a mixture of distorted corner and edge-sharing SZnCo3 trigonal pyramids.
