The structure described by MgV2(CrS4)2 crystallizes in the orthorhombic Imm2 space group. Mg(1) is bonded to two equivalent S(2) and two equivalent S(3) atoms to form MgS4 tetrahedra that share corners with six equivalent V(1)S6 octahedra and corners with six equivalent Cr(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 62-63°. V(1) is bonded to one S(1), one S(3), two equivalent S(2), and two equivalent S(4) atoms to form VS6 octahedra that share corners with three equivalent Mg(1)S4 tetrahedra, edges with two equivalent V(1)S6 octahedra, and edges with four equivalent Cr(1)S6 octahedra. Cr(1) is bonded to one S(2), one S(4), two equivalent S(1), and two equivalent S(3) atoms to form CrS6 octahedra that share corners with three equivalent Mg(1)S4 tetrahedra, edges with two equivalent Cr(1)S6 octahedra, and edges with four equivalent V(1)S6 octahedra. There are four inequivalent S sites. In the first S site, S(1) is bonded in a distorted T-shaped geometry to one V(1) and two equivalent Cr(1) atoms. In the second S site, S(2) is bonded to one Mg(1), two equivalent V(1), and one Cr(1) atom to form SMgV2Cr tetrahedra that share  a cornercorner with one S(2)MgV2Cr tetrahedra, corners with two equivalent S(3)MgVCr2 tetrahedra,  an edgeedge with one S(2)MgV2Cr tetrahedra, and edges with two equivalent S(3)MgVCr2 tetrahedra. In the third S site, S(3) is bonded to one Mg(1), one V(1), and two equivalent Cr(1) atoms to form SMgVCr2 tetrahedra that share  a cornercorner with one S(3)MgVCr2 tetrahedra, corners with two equivalent S(2)MgV2Cr tetrahedra,  an edgeedge with one S(3)MgVCr2 tetrahedra, and edges with two equivalent S(2)MgV2Cr tetrahedra. In the fourth S site, S(4) is bonded in a distorted T-shaped geometry to two equivalent V(1) and one Cr(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
