Magnetic Hysteresis in a Dysprosium Bis(amide) Complex.

ABSTRACT: Here, we present the synthesis and characterization of two mononuclear dysprosium molecules. The first complex is neutral and contains two triarylamide ligands coordinating to a Dy^III ion that is additionally ligated to a chloride anion, in the form of (NHAr*)₂DyCl (1). Treatment of 1 with Tl[BArF₂₄] prompted the removal of the chloride as TlCl from the first coordination sphere to afford the mononuclear Dy^III complex, [(NHAr*)₂Dy][BArF₂₄] (2), with a cationic [(NHAr*)₂Dy]⁺ core. 1 and 2 were investigated through single-crystal X-ray diffraction analysis, UV-vis spectroscopy, and SQUID magnetometry. Both compounds are single-molecule magnets with magnetic hysteresis. T
