A cluster‐forming ligand , p‐tert ‐butylsulfonylcalix[4]arene (H 4 L ), allows the formation of lanthanide wheels whose cluster cores contain eight lanthanide ions (Gd III , Sm III , Nd III , or Pr III ; shown in green in the picture) connected by L 4− ions, which act as both a tetradentate and a bisbidentate μ 3 ‐ligand, and eight bridging acetate groups. The wheels form by a “step‐by‐step” process via the mononuclear subunit {Ln( L )} − .
