Cu3SbS4 crystallizes in the cubic Fm-3m space group. Cu(1) is bonded in a distorted square co-planar geometry to four equivalent S(1) atoms. Sb(1) is bonded in a tetrahedral geometry to four equivalent S(1) atoms. S(1) is bonded to three equivalent Cu(1) and one Sb(1) atom to form a mixture of distorted corner and edge-sharing SCu3Sb tetrahedra.
