Macrocyclic pentagonal bipyramidal Dy(III) single-molecule magnets

We highlight the vast synthetic scope for macrocyclic engineering of magnetic anisotropy, generating a high performance pentagonal bipyramidal Dy(III) single-ion magnet where the weak equatorial ligand field is created entirely by using a macrocycle.

Hexagonal bipyramidal Dy(III) single-ion magnets

Combining a strong linear axial ligand field with a weak equatorial ligand field, by using the polydentate ligand LN6, reveals for the first time the exceptional uniaxial magnetic anisotropy possible for hexagonal bipyramidal geometry and opens up a route to further air-stable higher-order symmetry single-molecule magnets.

There is nothing wrong with being soft: using sulfur ligands to increase axiality in a Dy(III) single-ion magnet

A new air-stable sulfur-ligated Dy(III) single-ion magnet has been successfully isolated with Ueff = 638 K and hysteresis loops open up to 7 K. In silico studies show that the S co-ligands significantly boost the axiality and that Te- and Se-donors have the potential to further enhance the magnetic properties.
