Modulating Magnetic Performance in DyIII Single Ion Magnets With N5O2 Ligands

Year: 2024

Type: article

Abstract: ABSTRACT [Dy (LMe)(H2O)]CF3SO3·0.25H2O (1·0.25H2O), where H2LMe is the reported ligand 2,2′‐(((pyridine‐2,6‐diylbis (methylene))bis((pyridin‐2‐ylmethyl)azanediyl))bis (methylene))bis(4‐methylphenol), shows the DyIII ion in an N5O3 environment, with triangular dodecahedral geometry (D2d symmetry). 1·0.25H2O is a single ion magnet (SIM) with an energy barrier for spin reversal of 510 K, and open hysteresis loops up to 8 K. The magnetostructural comparison of 1·0.25H2O with some closely related complexes and with other eight‐coordinated SIMs with high energy barriers (> 300 K) allows to draw some conclusions to enhance the magnetic performance in these nanomagnets with non‐purely axial geometries. Ab initio calculations complement and support the experimental results.
