Figure 5
Shells of the 104 atom Samson cluster building the approximant cI160-R-Al5CuLi3 (Audier et al., 1988BB1). All shells are centred at the origin. Shells (a)–(c) form the 44 atom Bergman cluster. (a) Al/Cu icosahedron. (b) Li pentagondodecahedron. Its pentagons are capped by Al/Cu atoms forming an icosahedron with diameter similar to the dodecahedron (c). These two shells together form a triacontahedron. (d) Truncated icosahedron of Al/Cu atoms. (e) Li triacontahedron with Li atoms capping the hexagonal faces of the truncated icosahedron.
