The structure described by MgCrCoS4 is Spinel-derived structured and crystallizes in the orthorhombic Imma space group. Mg(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form MgS4 tetrahedra that share corners with six equivalent Cr(1)S6 octahedra and corners with six equivalent Co(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 57-63°. Cr(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form CrS6 octahedra that share corners with six equivalent Mg(1)S4 tetrahedra, edges with two equivalent Cr(1)S6 octahedra, and edges with four equivalent Co(1)S6 octahedra. Co(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form CoS6 octahedra that share corners with six equivalent Mg(1)S4 tetrahedra, edges with two equivalent Co(1)S6 octahedra, and edges with four equivalent Cr(1)S6 octahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded to one Mg(1), two equivalent Cr(1), and one Co(1) atom to form distorted SMgCr2Co tetrahedra that share corners with six equivalent S(1)MgCr2Co tetrahedra, corners with six equivalent S(2)MgCrCo2 tetrahedra,  an edgeedge with one S(1)MgCr2Co tetrahedra, and edges with two equivalent S(2)MgCrCo2 tetrahedra. In the second S site, S(2) is bonded to one Mg(1), one Cr(1), and two equivalent Co(1) atoms to form distorted SMgCrCo2 tetrahedra that share corners with six equivalent S(1)MgCr2Co tetrahedra, corners with six equivalent S(2)MgCrCo2 tetrahedra,  an edgeedge with one S(2)MgCrCo2 tetrahedra, and edges with two equivalent S(1)MgCr2Co tetrahedra. is represented by the CIF file [CIF]
