Syntheses, crystal structures, and magnetic properties of cyclic dimer Ln₂L₂ complexes constructed from (3-pyridinylmethoxy)phenyl-substituted nitronyl nitroxide ligands

Abstract

Herein, five lanthanide-radical cyclic dimer complexes have been obtained and complex Tb shows the relaxation behavior in zero dc field with an anisotropy barrier <italic>Δ</italic>/<italic>k</italic>_B = 21.6 K.
