Abstract

Two heteroleptic octahedral Dy(III) cis-aryloxide complexes, [Dy(OPh*)2(THF)3X] HOPh* = 2,6-bis(diphenyl-methyl)-4-tert-butylphenol; X = Cl (1), Br (2), have been characterised by multi-frequency electron paramagnetic resonance (EPR) spectroscopy to determine gz = 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.
