“…In recent years, lanthanide‐based compounds have been the forcus of research and applied in many fields, which are regarded as good candidates for constructing SMMs due to their unquenched orbital angular momentum as well as intrinsic magnetic anisotropy . Especially for Dy‐based complex, they were frequently utilized to pursue large anisotropic barrier in the research of SMMs because of the high S value ( S = 15/2) and large anisotropy of the 4f‐shell …”

Reaction of the Schiff base ligand H2L and dysprosium acetate result in a new planar Dy6 cluster [Dy6(μ3‐OH)L6(Ac)6]·MeOH (1) [H2L = N'‐(2‐hydroxybenzylidene)‐2‐(hydroxyimino)propanohydrazide, HAc = acetic acid], which was successfully structurally and magnetically characterized. Single‐crystal X‐ray diffraction analysis revealed that 1 contained a hexanuclear dysprosium cluster [Dy6], which is composed of four Dy3 triangular units. Magnetic measurements suggest that 1 displays single‐molecule magnet (SMM) behavior which is enhanced by applying a 4000 Oe direct‐current field. The effective anisotropic barrier Ueff/kB = 14.9 K and the pre‐exponential factor τ0 = 1.31 × 10–6 s are also obtained. This work may provide more insights for the design and investigation of lanthanide‐based SMMs.
