The material described by Ag8S crystallizes in the cubic F-43m space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to six equivalent Ag(1) and six equivalent Ag(2) atoms to form AgAg12 cuboctahedra that share corners with twelve equivalent Ag(1)Ag12 cuboctahedra, edges with twelve equivalent Ag(1)Ag12 cuboctahedra, edges with three equivalent S(1)Ag4 tetrahedra, and faces with six equivalent Ag(1)Ag12 cuboctahedra. In the second Ag site, Ag(2) is bonded in a single-bond geometry to six equivalent Ag(1) and one S(1) atom. S(1) is bonded to four equivalent Ag(2) atoms to form SAg4 tetrahedra that share edges with twelve equivalent Ag(1)Ag12 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
