Isolation of a Bent Dysprosium Bis(amide) Single-Molecule Magnet.

ABSTRACT: The isolation of formally two-coordinate lanthanide (Ln) complexes is synthetically challenging, due to predominantly ionic Ln bonding regimes favoring high coordination numbers. In 2015, it was predicted that a near-linear dysprosium bis(amide) cation [Dy{N(SiⁱPr₃)₂}₂]⁺ could provide a single-molecule magnet (SMM) with an energy barrier to magnetic reversal (U_eff) of up to 2600 K, a 3-fold increase of the record U_eff for a Dy SMM at the time; this work showed a potential route to SMMs that can provide high-density data storage at higher temperatures. However, synthetic routes to a Dy complex containing only two monodentate ligands have not previously been realized. Here, we report the synthesis of t
