Building blocks of i-YbCd5.7 and related cAPs. The red and grey spheres represent Yb and Cd atoms, respectively. (a) The shell structure of the Tsai-type cluster (RTH unit). (b) The atomic decoration of the DFP unit. (c,d) The arrangements of Tsai-type clusters in the 1/1 (YbCd6) and 2/1 (YbCd5.8) cAPs, respectively, depicted using the third icosahedral shells. (e,f) Pairs of Tsai-type clusters connected by b and c linkages, respectively, depicted using the outermost polyhedra. |
