Cover Picture: High-Spin Cyclopentadienyl Complexes: A Single-Molecule Magnet Based on the Aryl-Iron(II) Cyclopentadienyl Type (Chem. Eur. J. 17/2011)

摘要

A mononuclear high-spin iron(II) complex coordinated by a pentaisopropylcyclopentadienide and an aryl group has been prepared and characterized by X-ray diffraction analysis. In their Communication on page 4700 ff., Y. Lan, H. Sitzmann et al. present AC magnetic studies in which this complex shows slow magnetic relaxation and exhibits the characteristics of a single-molecule magnet.
