The crystal structure described by Mg(Cr2S5)2 crystallizes in the monoclinic Pm space group. Mg(1) is bonded to one S(4), one S(6), and two equivalent S(5) atoms to form MgS4 trigonal pyramids that share corners with four equivalent Cr(4)S5 trigonal bipyramids, corners with two equivalent Mg(1)S4 trigonal pyramids, and  an edgeedge with one Cr(3)S5 trigonal bipyramid. There are four inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 5-coordinate geometry to one S(10), one S(2), one S(9), and two equivalent S(1) atoms. In the second Cr site, Cr(2) is bonded to one S(1), one S(7), one S(8), and two equivalent S(2) atoms to form distorted corner-sharing CrS5 trigonal bipyramids. In the third Cr site, Cr(3) is bonded to one S(4), one S(6), one S(8), and two equivalent S(3) atoms to form distorted CrS5 trigonal bipyramids that share  a cornercorner with one Cr(2)S5 trigonal bipyramid, corners with two equivalent Cr(3)S5 trigonal bipyramids, edges with two equivalent Cr(4)S5 trigonal bipyramids, and  an edgeedge with one Mg(1)S4 trigonal pyramid. In the fourth Cr site, Cr(4) is bonded to one S(3), one S(5), one S(9), and two equivalent S(4) atoms to form CrS5 trigonal bipyramids that share corners with two equivalent Cr(4)S5 trigonal bipyramids, corners with four equivalent Mg(1)S4 trigonal pyramids, and edges with two equivalent Cr(3)S5 trigonal bipyramids. There are ten inequivalent S sites. In the first S site, S(1) is bonded in a distorted trigonal non-coplanar geometry to one Cr(2) and two equivalent Cr(1) atoms. In the second S site, S(2) is bonded in a trigonal non-coplanar geometry to one Cr(1) and two equivalent Cr(2) atoms. In the third S site, S(3) is bonded in a trigonal non-coplanar geometry to one Cr(4) and two equivalent Cr(3) atoms. In the fourth S site, S(4) is bonded to one Mg(1), one Cr(3), and two equivalent Cr(4) atoms to form distorted corner-sharing SMgCr3 trigonal pyramids. In the fifth S site, S(5) is bonded in a trigonal non-coplanar geometry to two equivalent Mg(1) and one Cr(4) atom. In the sixth S site, S(6) is bonded in an L-shaped geometry to one Mg(1) and one Cr(3) atom. In the seventh S site, S(7) is bonded in a single-bond geometry to one Cr(2) atom. In the eighth S site, S(8) is bonded in a bent 150 degrees geometry to one Cr(2) and one Cr(3) atom. In the ninth S site, S(9) is bonded in a bent 150 degrees geometry to one Cr(1) and one Cr(4) atom. In the tenth S site, S(10) is bonded in a single-bond geometry to one Cr(1) atom. is represented by the CIF card [CIF]
