The structure described by Ag3Sb is beta-derived structured and crystallizes in the hexagonal P-6m2 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 six equivalent Ag(1)Ag12 cuboctahedra, corners with twelve equivalent Sb(1)Ag6Sb6 cuboctahedra, edges with six equivalent Ag(1)Ag12 cuboctahedra, edges with twelve equivalent Ag(2)Ag9Sb3 cuboctahedra, faces with two equivalent Sb(1)Ag6Sb6 cuboctahedra, faces with six equivalent Ag(1)Ag12 cuboctahedra, and faces with twelve equivalent Ag(2)Ag9Sb3 cuboctahedra. In the second Ag site, Ag(2) is bonded to three equivalent Ag(1), six equivalent Ag(2), and three equivalent Sb(1) atoms to form AgAg9Sb3 cuboctahedra that share corners with eighteen equivalent Ag(2)Ag9Sb3 cuboctahedra, edges with six equivalent Ag(1)Ag12 cuboctahedra, edges with six equivalent Ag(2)Ag9Sb3 cuboctahedra, edges with six equivalent Sb(1)Ag6Sb6 cuboctahedra, faces with six equivalent Ag(1)Ag12 cuboctahedra, faces with six equivalent Sb(1)Ag6Sb6 cuboctahedra, and faces with eight equivalent Ag(2)Ag9Sb3 cuboctahedra. Sb(1) is bonded to six equivalent Ag(2) and six equivalent Sb(1) atoms to form SbAg6Sb6 cuboctahedra that share corners with six equivalent Sb(1)Ag6Sb6 cuboctahedra, corners with twelve equivalent Ag(1)Ag12 cuboctahedra, edges with six equivalent Sb(1)Ag6Sb6 cuboctahedra, edges with twelve equivalent Ag(2)Ag9Sb3 cuboctahedra, faces with two equivalent Ag(1)Ag12 cuboctahedra, faces with six equivalent Sb(1)Ag6Sb6 cuboctahedra, and faces with twelve equivalent Ag(2)Ag9Sb3 cuboctahedra. is represented by the CIF file [CIF]
