Al3Sn is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Al(1) is bonded to eight equivalent Al(1) and four equivalent Sn(1) atoms to form distorted AlAl8Sn4 cuboctahedra that share corners with twelve equivalent Al(1)Al8Sn4 cuboctahedra, edges with eight equivalent Sn(1)Al12 cuboctahedra, edges with sixteen equivalent Al(1)Al8Sn4 cuboctahedra, faces with four equivalent Sn(1)Al12 cuboctahedra, and faces with fourteen equivalent Al(1)Al8Sn4 cuboctahedra. Sn(1) is bonded to twelve equivalent Al(1) atoms to form SnAl12 cuboctahedra that share corners with twelve equivalent Sn(1)Al12 cuboctahedra, edges with twenty-four equivalent Al(1)Al8Sn4 cuboctahedra, faces with six equivalent Sn(1)Al12 cuboctahedra, and faces with twelve equivalent Al(1)Al8Sn4 cuboctahedra.
