Atomic decoration of rhombohedral units in the i-CdYb refined model with Tsai clusters. The orientation of each unit is given by three vectors of icosahedral setting, directed toward the vertices by a common face of the icosahedron. All shells of the Tsai cluster are given individually for clarity. The shells are dodecahedron (#1), icosahedron (#2), icosidodecahedron (#3) and rhombic triacontahedron (#4). In most cases, there is a Yb atom at the center of the clusters. |
