The structure described by MgVCu3S4 crystallizes in the trigonal R3m space group. Mg(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent S(1) atoms. V(1) is bonded in a tetrahedral geometry to one S(2) and three equivalent S(1) atoms. Cu(1) is bonded in a 4-coordinate geometry to one S(2) and three equivalent S(1) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a distorted pentagonal planar geometry to one Mg(1), one V(1), and three equivalent Cu(1) atoms. In the second S site, S(2) is bonded in a distorted tetrahedral geometry to one V(1) and three equivalent Cu(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
