Figure 4
Distribution of the Al polyhedra built around the Au1/Ir1 (left) and Au2/Ir2 (right) atomic positions in the unit cell of the Al₉(Au;Ir)₄ compound reported here. Au1/Ir1 polyhedra are connected by sharing Al3 positions along the c axis and Al1–Al1 or Al2–Al2 edges in the (ab) plane. Au2/Ir2 polyhedra are only connected in the (ab) plane by sharing Al3 positions or Al1–Al2 edges.
