Abstract

A cluster-forming ligsnd, p-tert-butylsulfonylcalix[4]arene (H 4L), allows the formation of lanthanide wheels whose cluster cores contain eight lanthanide ions (GdIII, SmIII, Nd III or PrIII; shown in green in the picture) connected by L4- ions, which act as both a tetradentate and a bisbidentate μ3-ligand, and eight bridging acetate groups. The wheels form by a "step-by-step" process via the mononuclear subunit {Ln(L)} -.
