The material structure described by WCu6SnS8 is Stannite-like structured and crystallizes in the tetragonal P-4m2 space group. W(1) is bonded to four equivalent S(2) atoms to form WS4 tetrahedra that share corners with four equivalent Cu(2)S4 tetrahedra and corners with eight equivalent Cu(1)S4 tetrahedra. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form CuS4 tetrahedra that share corners with two equivalent W(1)S4 tetrahedra, corners with two equivalent Sn(1)S4 tetrahedra, corners with four equivalent Cu(1)S4 tetrahedra, and corners with four equivalent Cu(2)S4 tetrahedra. In the second Cu site, Cu(2) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form CuS4 tetrahedra that share corners with two equivalent W(1)S4 tetrahedra, corners with two equivalent Sn(1)S4 tetrahedra, and corners with eight equivalent Cu(1)S4 tetrahedra. Sn(1) is bonded to four equivalent S(1) atoms to form SnS4 tetrahedra that share corners with four equivalent Cu(2)S4 tetrahedra and corners with eight equivalent Cu(1)S4 tetrahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded to one Cu(2), two equivalent Cu(1), and one Sn(1) atom to form SCu3Sn tetrahedra that share corners with six equivalent S(1)Cu3Sn tetrahedra and corners with six equivalent S(2)Cu3W tetrahedra. In the second S site, S(2) is bonded to one W(1), one Cu(2), and two equivalent Cu(1) atoms to form SCu3W tetrahedra that share corners with six equivalent S(1)Cu3Sn tetrahedra and corners with six equivalent S(2)Cu3W tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
