High-Spin Cyclopentadienyl Complexes: A Single-Molecule Magnet Based on the Aryl-Iron(II) Cyclopentadienyl Type

The mononuclear high‐spin iron(II) complex 1, coordinated by a pentaisopropylcyclopentadienide and an aryl group (see graphic), has been prepared and characterized by X‐ray diffraction analysis. AC magnetic studies have revealed that this species exhibits slow magnetic relaxation and has the charact...

Beschreibung
Zusammenfassung:The mononuclear high‐spin iron(II) complex 1, coordinated by a pentaisopropylcyclopentadienide and an aryl group (see graphic), has been prepared and characterized by X‐ray diffraction analysis. AC magnetic studies have revealed that this species exhibits slow magnetic relaxation and has the characteristics of a single‐molecule magnet.
