Synthetic aspects are discussed. A comprehensive topological analysis of all reported ZnII/LnIII CCs with a core nuclearity of four and above is presented and identifies that families (4–6) and (7–9) are the first examples of the 2,3,4M6–1 motif in ZnII/LnIII chemistry. Magnetic studies are presented for the DyIII analogues (1, 7, and 10) are presented, 7 demonstrates field-induced slow relaxation of the magnetization. Fluorescence studies are also discussed.
