Figure 1
Clusters in hP386-Al57.4Cu3.6Ta39.0. Light blue, blue and brown colored atoms correspond to Al, Al/Cu and Ta sites, respectively. The three shells of the F3260 cluster are shown on the top (blue polyhedra) and those of the F3974 cluster in the middle (red polyhedra). The packing of the clusters is shown below: on the left the ABAC stacking in the c direction is shown, where A layers are comprised of differently oriented F3260 clusters (blue) and B and C layers of F3974 clusters (red). The full packing is depicted on the right, where also the intermediate clusters FK2816 and FK2615 in light blue and violet, respectively, are visualized.
