The compound described by Cu3AsS4 is Lavarevi\'{c}ite structured and crystallizes in the cubic P-43m space group. Cu(1) is bonded to four equivalent S(1) atoms to form CuS4 tetrahedra that share corners with four equivalent As(1)S4 tetrahedra and corners with eight equivalent Cu(1)S4 tetrahedra. As(1) is bonded to four equivalent S(1) atoms to form AsS4 tetrahedra that share corners with twelve equivalent Cu(1)S4 tetrahedra. S(1) is bonded to three equivalent Cu(1) and one As(1) atom to form corner-sharing SCu3As tetrahedra. is represented by the CIF file [CIF]
