Wheel‐Shaped Er^IIIZn^II₃ Single‐Molecule Magnet: A Macrocyclic Approach to Designing Magnetic Anisotropy

Abstract

Designer SMM: An ErIII-based single-molecule magnet (SMM) was synthesized by designing the ligand-field anisotropy around an ErIII ion in an equatorial arrangement of donors using a rigid and planar macrocyclic Schiff base ligand including three ZnII ions. The resulting ErIIIZnII3 complex (see picture; C gray, O red, N blue) behaves as a SMM with an energy barrier of 24.6(9) K for flipping of the molecular magnetic moment.
