The material structure described by TbLa3 is Copper-derived structured and crystallizes in the tetragonal I4/mmm space group. Tb(1) is bonded to four equivalent La(2) and eight equivalent La(1) atoms to form TbLa12 cuboctahedra that share corners with four equivalent Tb(1)La12 cuboctahedra, corners with eight equivalent La(2)La8Tb4 cuboctahedra, edges with eight equivalent Tb(1)La12 cuboctahedra, edges with sixteen equivalent La(1)La8Tb4 cuboctahedra, faces with four equivalent Tb(1)La12 cuboctahedra, faces with six equivalent La(2)La8Tb4 cuboctahedra, and faces with eight equivalent La(1)La8Tb4 cuboctahedra. There are two inequivalent La sites. In the first La site, La(1) is bonded to four equivalent Tb(1), four equivalent La(1), and four equivalent La(2) atoms to form LaLa8Tb4 cuboctahedra that share corners with twelve equivalent La(1)La8Tb4 cuboctahedra, edges with eight equivalent Tb(1)La12 cuboctahedra, edges with eight equivalent La(1)La8Tb4 cuboctahedra, edges with eight equivalent La(2)La8Tb4 cuboctahedra, faces with four equivalent Tb(1)La12 cuboctahedra, faces with four equivalent La(2)La8Tb4 cuboctahedra, and faces with ten equivalent La(1)La8Tb4 cuboctahedra. In the second La site, La(2) is bonded to four equivalent Tb(1) and eight equivalent La(1) atoms to form LaLa8Tb4 cuboctahedra that share corners with four equivalent La(2)La8Tb4 cuboctahedra, corners with eight equivalent Tb(1)La12 cuboctahedra, edges with eight equivalent La(2)La8Tb4 cuboctahedra, edges with sixteen equivalent La(1)La8Tb4 cuboctahedra, faces with four equivalent La(2)La8Tb4 cuboctahedra, faces with six equivalent Tb(1)La12 cuboctahedra, and faces with eight equivalent La(1)La8Tb4 cuboctahedra. is represented by the CIF card [CIF]
