The structure described by AcLa3 is Copper-derived structured and crystallizes in the tetragonal I4/mmm space group. Ac(1) is bonded to four equivalent La(2) and eight equivalent La(1) atoms to form AcLa12 cuboctahedra that share corners with four equivalent Ac(1)La12 cuboctahedra, corners with eight equivalent La(2)Ac4La8 cuboctahedra, edges with eight equivalent Ac(1)La12 cuboctahedra, edges with sixteen equivalent La(1)Ac4La8 cuboctahedra, faces with four equivalent Ac(1)La12 cuboctahedra, faces with six equivalent La(2)Ac4La8 cuboctahedra, and faces with eight equivalent La(1)Ac4La8 cuboctahedra. There are two inequivalent La sites. In the first La site, La(1) is bonded to four equivalent Ac(1), four equivalent La(1), and four equivalent La(2) atoms to form LaAc4La8 cuboctahedra that share corners with twelve equivalent La(1)Ac4La8 cuboctahedra, edges with eight equivalent Ac(1)La12 cuboctahedra, edges with eight equivalent La(1)Ac4La8 cuboctahedra, edges with eight equivalent La(2)Ac4La8 cuboctahedra, faces with four equivalent Ac(1)La12 cuboctahedra, faces with four equivalent La(2)Ac4La8 cuboctahedra, and faces with ten equivalent La(1)Ac4La8 cuboctahedra. In the second La site, La(2) is bonded to four equivalent Ac(1) and eight equivalent La(1) atoms to form LaAc4La8 cuboctahedra that share corners with four equivalent La(2)Ac4La8 cuboctahedra, corners with eight equivalent Ac(1)La12 cuboctahedra, edges with eight equivalent La(2)Ac4La8 cuboctahedra, edges with sixteen equivalent La(1)Ac4La8 cuboctahedra, faces with four equivalent La(2)Ac4La8 cuboctahedra, faces with six equivalent Ac(1)La12 cuboctahedra, and faces with eight equivalent La(1)Ac4La8 cuboctahedra. is represented by the CIF card [CIF]
