The structure described by TlAl3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Tl(1) is bonded to twelve equivalent Al(1) atoms to form TlAl12 cuboctahedra that share corners with twelve equivalent Tl(1)Al12 cuboctahedra, edges with twenty-four equivalent Al(1)Al8Tl4 cuboctahedra, faces with six equivalent Tl(1)Al12 cuboctahedra, and faces with twelve equivalent Al(1)Al8Tl4 cuboctahedra. Al(1) is bonded to four equivalent Tl(1) and eight equivalent Al(1) atoms to form AlAl8Tl4 cuboctahedra that share corners with twelve equivalent Al(1)Al8Tl4 cuboctahedra, edges with eight equivalent Tl(1)Al12 cuboctahedra, edges with sixteen equivalent Al(1)Al8Tl4 cuboctahedra, faces with four equivalent Tl(1)Al12 cuboctahedra, and faces with fourteen equivalent Al(1)Al8Tl4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
