A fluorobenzene-bound dysprosium half-sandwich dication single-molecule magnet.

ABSTRACT: Dysprosium single-molecule magnets (SMMs) with two mutually trans-anionic ligands have shown large crystal field (CF) splitting, giving record effective energy barriers to magnetic reversal (U _eff) and hysteresis temperatures (T _H). However, these complexes tend to be bent, imposing a transverse field that reduces the purity of the m _J projections of the CF states and promotes magnetic relaxation. A complex with only one charge-dense anionic ligand could have more pure CF states, and thus high U _eff and T _H. Here we report an SMM with this topology, a half-sandwich Dy(iii) complex [Dy(Cp*)(FPh)₆][{Al[OC(CF₃)₃]₃}₂(μ-F)]₂ (1
