Homochiral Dy III complexes : By changing the ligand‐to‐metal ratio, enantiomeric pairs of a Dy III complex of different nuclearity could be obtained. The mono‐ and dinuclear complexes exhibit characteristics of single‐molecule magnets and different slow magnetic relaxation processes. In addition, the dinuclear complexes (see picture) exhibit ferroelectric behavior, thus representing the first chiral polynuclear lanthanide‐based single‐molecule magnets with ferroelectric properties.
