Polyoxometalates as advanced-performance anions for ∼D5h Dy(iii) single-ion magnets

Abstract

We enhance single-ion magnet (SIM) magnetisation reversal barriers by engineering the second coordination sphere, substituting conventional small monoanions with a bulky polyoxometalate (POM) trianion. Importantly, our approach serves as a model for creating new high-performance multifunctional hybrid materials.
