Observation of field-induced single-ion magnet behavior in an octahedral dysprosium complex with a strong ligand field

By employing oxygen-containing ligands with strong coordination ability, a mononuclear six-coordinate Dy-III complex [Dy(Ph3PO)(3)(OPhCl2NO2)(3)] (1) (Ph3PO = triphenylphosphine oxide, Cl2NO2PhOH = 2,6-dichloro-4-nitrophenol) with an octahedral DyO6 coordination environment has been successfully synthesized. Magnetic measurements reveal that complex 1 exhibits field-induced slow magnetic relaxation with an energy barrier of 21.3 K, which provides a rare case for mononuclear octahedral Ln-based complexes with slow magnetic relaxation behavior.
