Slow Magnetic Relaxation in a Lanthanide-[1]Metallocenophane Complex

摘要

The first example of a lanthanide metal-locenophane complex has been isolated as [Li(THF)_4]-[DyFc_3Li_2(THF)_2] (I). The molecular structure of complex 1 differs dramatically from those of main group and transition metal ferrocenophane complexes and features a distorted trigonal prismatic geometry around the Dy(III) ion and close intramolecular Dy-Fe distances. Furthermore, complex 1 exhibits all characteristics of a soft single-molecule magnet.
