Direct characterisation of <i>m</i><sub><i>J</i></sub> = ±15/2 ground state in octahedral Dy(<scp>iii</scp>) single-molecule magnets
Two heteroleptic octahedral Dy(III) <i>cis</i>-aryloxide complexes, [Dy(OPh*)<sub>2</sub>(THF)<sub>3</sub>X] {HOPh* = 2,6-bis(diphenyl-methyl)-4-<i>tert</i>-butylphenol; X = Cl (1), Br (2)}, have been characterised by multi-frequency electron paramagnetic resonance (EPR) spectroscopy to determine <i>g</i><sub><i>z</i></sub> = 18.9(1) for 1 and 18.3(6) for 2. These are rare examples of Dy(III) single-molecule magnets that have observable EPR spectra.
