Slow Magnetic Relaxation of Lanthanide(III) Complexes with a Helical Ligand

Slow Magnetic Relaxation of Lanthanide(III) Complexes with a Helical Ligand

Isostructural Ln(III) mononuclear complexes [Ln(NO3)2L]PF6·MeCN (Ln = Nd, Tb, or Dy; L denotes a helical hexa-dentate ligand) were synthesized, and their slow magnetic relaxation behavior was investigated. In these complexes, oblate-type Ln(III) ions are located in an axially stressed ligand field w...

Zusammenfassung:Isostructural Ln(III) mononuclear complexes [Ln(NO3)2L]PF6·MeCN (Ln = Nd, Tb, or Dy; L denotes a helical hexa-dentate ligand) were synthesized, and their slow magnetic relaxation behavior was investigated. In these complexes, oblate-type Ln(III) ions are located in an axially stressed ligand field with two nitrate anions, and can exhibit single-molecule magnet (SMM) behavior. Field-induced SMM behavior was observed for Nd(III) and Dy(III) complexes under an applied bias DC field of 1000 Oe.
