Figure 6
Atomic decoration of rhombohedral units in the i-CdYb refined model with the dual AKNt and Bergman clusters. The orientation of each unit is given by three vectors of icosahedral setting, directed toward the vertices a common face of the icosahedron. All shells of the Bergman cluster are given individually for clarity. The shells are icosahedron (#1), dodecahedron (#2), icosahedron (#3) (shells #2 and #3 form a rhombic triacontahedron), soccerball polyhedron (#4) and rhombic triacontahedron (#5). In most cases, there is a Cd atom in the center of the cluster. The disordered tetrahedron treated as a partially occupied icosahedron can be seen in the vertices of PR and OR.
