The structure described by Ag3Sb is beta Cu3Ti structured and crystallizes in the orthorhombic Pmmn space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to eight equivalent Ag(2) and four equivalent Sb(1) atoms to form AgAg8Sb4 cuboctahedra that share corners with two equivalent Ag(1)Ag8Sb4 cuboctahedra, corners with eight equivalent Ag(2)Ag8Sb4 cuboctahedra, corners with eight equivalent Sb(1)Ag12 cuboctahedra, edges with six equivalent Ag(1)Ag8Sb4 cuboctahedra, edges with twelve equivalent Ag(2)Ag8Sb4 cuboctahedra, faces with six equivalent Ag(1)Ag8Sb4 cuboctahedra, faces with six equivalent Sb(1)Ag12 cuboctahedra, and faces with eight equivalent Ag(2)Ag8Sb4 cuboctahedra. In the second Ag site, Ag(2) is bonded to four equivalent Ag(1), four equivalent Ag(2), and four equivalent Sb(1) atoms to form AgAg8Sb4 cuboctahedra that share corners with four equivalent Ag(1)Ag8Sb4 cuboctahedra, corners with four equivalent Sb(1)Ag12 cuboctahedra, corners with ten equivalent Ag(2)Ag8Sb4 cuboctahedra, edges with six equivalent Ag(1)Ag8Sb4 cuboctahedra, edges with six equivalent Ag(2)Ag8Sb4 cuboctahedra, edges with six equivalent Sb(1)Ag12 cuboctahedra, faces with four equivalent Ag(1)Ag8Sb4 cuboctahedra, faces with four equivalent Sb(1)Ag12 cuboctahedra, and faces with twelve equivalent Ag(2)Ag8Sb4 cuboctahedra. Sb(1) is bonded to four equivalent Ag(1) and eight equivalent Ag(2) atoms to form SbAg12 cuboctahedra that share corners with two equivalent Sb(1)Ag12 cuboctahedra, corners with eight equivalent Ag(1)Ag8Sb4 cuboctahedra, corners with eight equivalent Ag(2)Ag8Sb4 cuboctahedra, edges with six equivalent Sb(1)Ag12 cuboctahedra, edges with twelve equivalent Ag(2)Ag8Sb4 cuboctahedra, faces with six equivalent Ag(1)Ag8Sb4 cuboctahedra, faces with six equivalent Sb(1)Ag12 cuboctahedra, and faces with eight equivalent Ag(2)Ag8Sb4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
