From: 2D crystal structure and anisotropic magnetism of GdAu6.75−xAl0.5+x (x ≈ 0.54)

Crystal structure of the 1/1 AC. (a) Pair of Gd(Au/Al)16 polyhedra condensed via a common triangle, (b) arrangement of Gd(Au/Al)16 polyhedra and AlAu8 cubes in the unit cell and (c) Gd partial structure. Nearest Gd–Gd interatomic distances are drawn as red lines and their numbers are listed. The green lines highlight the connectivity of Gd atoms into icosahedral shells in Tsai clusters.
