Abstract

We generate a new air-stable pseudo-D <subscript>5h</subscript> Dy(iii) Single-Molecule Magnet (U <subscript>eff</subscript> = 1108 K, T <subscript>B</subscript> = 14 K) by combining a weak equatorial ligand field from a macrocyclic L <superscript>N5</superscript> ligand with a strong axial ligand field. Based on our synthetic blueprint, we use ab initio calculations to show the vast scope for macrocyclic engineering of magnetic anisotropy.
