Mg(CrS2)4 crystallizes in the monoclinic Cm space group. Mg(1) is bonded in a 4-coordinate geometry to one S(1), one S(6), and two equivalent S(2) atoms. There are three inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one S(1), one S(3), one S(4), one S(5), and one S(6) atom to form distorted edge-sharing CrS5 trigonal bipyramids. In the second Cr site, Cr(2) is bonded to one S(3), two equivalent S(2), and two equivalent S(5) atoms to form distorted edge-sharing CrS5 trigonal bipyramids. In the third Cr site, Cr(3) is bonded in a 5-coordinate geometry to one S(4), two equivalent S(2), and two equivalent S(5) atoms. There are six inequivalent S sites. In the first S site, S(1) is bonded in a distorted T-shaped geometry to one Mg(1) and two equivalent Cr(1) atoms. In the second S site, S(2) is bonded in a 3-coordinate geometry to one Mg(1), one Cr(2), and one Cr(3) atom. In the third S site, S(3) is bonded in a distorted T-shaped geometry to one Cr(2) and two equivalent Cr(1) atoms. In the fourth S site, S(4) is bonded in a distorted T-shaped geometry to one Cr(3) and two equivalent Cr(1) atoms. In the fifth S site, S(5) is bonded in a distorted T-shaped geometry to one Cr(1), one Cr(2), and one Cr(3) atom. In the sixth S site, S(6) is bonded in a distorted T-shaped geometry to one Mg(1) and two equivalent Cr(1) atoms.
