Abstract

The syntheses and magnetic properties of the first family of p-semiquinone-radical-bridged lanthanide complexes with crystal structures, sharing formula {Ln[(QMe₄)^•-Cl₂(THF)₃]}₂·solvent (Ln = Tb, Dy, Ho, Er, Tm and Yb; H₂QMe₄= 2,3,5,6-tetramethylhydroquinone), are reported. The semiquinone-radical motif is formed by oxidizing hydroquinone with FeCl₃instead of reducing quinone with only variable-valence lanthanide ions and is therefore applicable to most rare-earth systems. The Dy(III) analogue exhibits a two-step slow relaxation of magnetization behavior under an applied magnetic field, being the first lanthanide p-semiquinone single-molecule magnet.
