CuAsS crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Cu3+ is bonded to one As1- and three equivalent S2- atoms to form CuAsS3 tetrahedra that share a cornercorner with one SCu3As tetrahedra and corners with six equivalent CuAsS3 tetrahedra. The Cu–As bond length is 2.41 Å. All Cu–S bond lengths are 2.30 Å. As1- is bonded in a 2-coordinate geometry to one Cu3+, two equivalent As1-, and one S2- atom. Both As–As bond lengths are 2.55 Å. The As–S bond length is 2.30 Å. S2- is bonded to three equivalent Cu3+ and one As1- atom to form SCu3As tetrahedra that share a cornercorner with one CuAsS3 tetrahedra and corners with six equivalent SCu3As tetrahedra.
