MgVCoS4 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 V(1)S6 octahedra and corners with six equivalent Co(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 56-62°. V(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form VS6 octahedra that share corners with six equivalent Mg(1)S4 tetrahedra, edges with two equivalent V(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 V(1)S6 octahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to one Mg(1), two equivalent V(1), and one Co(1) atom. In the second S site, S(2) is bonded to one Mg(1), one V(1), and two equivalent Co(1) atoms to form a mixture of distorted corner and edge-sharing SMgVCo2 tetrahedra.
