Figure 6
Resulting atomic structure of i-ScZn7.33. (a) An example of an 80 × 80 × 40 Å3 slab of the refined i-ScZn7.33 structure normal to a fivefold axis. White lines indicate RTH shells. (b) Tsai-type RTH cluster shells with the local configuration (12, 7, 5). The red and blue lines indicate b- and c-linkages, respectively. (c) Dodecahedron shell at (12, 7, 5) and icosidodecahedron shell in the neighbouring RTH cluster, linked by c-linkage. The green line indicates the overlapping part of the RTH shells, defining an oblate rhombohedraon. The yellow lines indicate the Zn8 cube. |
