Sn3Sb is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Sn(1) is bonded to eight equivalent Sn(1) and four equivalent Sb(1) atoms to form SnSn8Sb4 cuboctahedra that share corners with twelve equivalent Sn(1)Sn8Sb4 cuboctahedra, edges with eight equivalent Sb(1)Sn12 cuboctahedra, edges with sixteen equivalent Sn(1)Sn8Sb4 cuboctahedra, faces with four equivalent Sb(1)Sn12 cuboctahedra, and faces with fourteen equivalent Sn(1)Sn8Sb4 cuboctahedra. Sb(1) is bonded to twelve equivalent Sn(1) atoms to form SbSn12 cuboctahedra that share corners with twelve equivalent Sb(1)Sn12 cuboctahedra, edges with twenty-four equivalent Sn(1)Sn8Sb4 cuboctahedra, faces with six equivalent Sb(1)Sn12 cuboctahedra, and faces with twelve equivalent Sn(1)Sn8Sb4 cuboctahedra.
