MgVCu3S4 crystallizes in the cubic P-43m space group. Mg(1) is bonded to four equivalent S(1) atoms to form MgS4 tetrahedra that share corners with four equivalent V(1)S4 tetrahedra and corners with twelve equivalent Cu(1)S4 tetrahedra. V(1) is bonded to four equivalent S(1) atoms to form VS4 tetrahedra that share corners with four equivalent Mg(1)S4 tetrahedra and edges with six equivalent Cu(1)S4 tetrahedra. Cu(1) is bonded to four equivalent S(1) atoms to form distorted CuS4 tetrahedra that share corners with four equivalent Mg(1)S4 tetrahedra, corners with eight equivalent Cu(1)S4 tetrahedra, and edges with two equivalent V(1)S4 tetrahedra. S(1) is bonded in a distorted pentagonal planar geometry to one Mg(1), one V(1), and three equivalent Cu(1) atoms.
