  • Descrição: Calix[4]arenes are versatile ligands that, whilst also serving other purposes, can act as platforms for the synthesis of a wide range of 3d, 4f, and 3d–4f polymetallic clusters. The empirical metal ion binding rules established for calix[4]arene are closely mirrored by bis‐calix[4]arene, a relatively new ligand in which two equivalents of the former are directly tethered at a methylene bridge position. The direct tethering within bis‐calix[4]arene gives rise to some structural features that are related to calix[4]arene coordination chemistry, but the prevailing clusters have fascinating new topologies and coordination behaviors. Here, we present the synthesis of a family of new bis‐calix[4]arene‐supported 3d–4f clusters, as well as their structural characterization and magnetic properties. Comparison is drawn with calix[4]arene coordination chemistry, showing logical extension of common structural fragments and cluster capping behaviors upon moving to bis‐calix[4]arene. This approach therefore holds great potential for tuning cluster formation and composition at a high level through subsequent ligand alteration. Bis‐calix[4]arene is a versatile ligand that has been used to form a new family of 3d–4f polymetallic clusters. Empirical metal ion binding rules established for calix[4]arene are closely mirrored in this ligand, suggesting that one may use coordination preferences and ligand alteration/design in order to tune both cluster formation and composition at a high level in complex multi‐component systems.
