Abstract

We report the synthesis of the lanthanide-(bis)boryloxide complex [Dy{OB(NArCH)₂}₂(THF)₄][BPh₄] (2Dy, Ar = 2,6-Prⁱ₂C₆H₃), with idealised D_4h@Dy(III) point-group symmetry. Complex 2Dy exhibits single-molecule magnetism (SMM), with one of the highest energy barriers (U_eff = 1565(298) K) of any six-coordinate lanthanide-SMM. Complex 2Dy validates electrostatic model predictions, informing the future design of lanthanide-SMMs.
