Calix[ n ]arenes offer ideal chemical functionality through the polyphenolic lower rim to construct nano-sized coordination clusters with lanthanide (Ln) metal ions ( e.g. , NdIII10, GdIII8). However, the number of metal centers they can accommodate is still limited compared to that achievable with smaller ligands ( e.g. , GdIII140, GdIII104). Here, we exploit a combination of the "anion template strategy" and "templating ligands" to synthesise three highly symmetric ( D 3h , trigonal planar) LnIII18 (Ln = La, Nd, and Gd) systems, representing the largest calix[ n ]arene-based coordination clusters yet...
