Influence of weakly coordinating anions binding to the hexa-tert-butyl dysprosocenium cation.

ABSTRACT: Complexes containing isolated dysprosocenium cations, [Dy(Cp^R)₂][WCA] (Cp^R = substituted cyclopentadienyl, WCA = weakly coordinating anion), have recently emerged as leading examples of high-temperature single-molecule magnets (SMMs) due to a combination of the axial orientation and rigidity of the Cp^R rings. However, our understanding of the effects of transverse fields on the magnetic properties of [Dy(Cp^R)₂]⁺ cations is underdeveloped. Here we investigate the impact of equatorially-bound WCAs via the synthesis of the Dy(III) bis-Cp^R complexes [Dy(Cp^ttt)₂{AlCl[OC(CF₃)₃]₃-κ-Cl}] (1) and [Dy(Cp^ttt)₂{AlCl(C_2</
