Magneto-structural correlations in a series of lanthanide polyoxometalates (POMs) with pentagonal bipyramidal symmetry, namely, [Ln(NMP)(PWO)][PWO] (NMP is N-methyl pyrrolidone), were studied in detail experimentally combined with theoretical calculations. Furthermore, two types of Dy-based complexes with pentagonal bipyramidal symmetry were built to discuss the dependence of the theoretical energy barriers with the axial Dy-O bond lengths when the magnetic axes in ground Kramers doublet are along the axial orientation or on the equatorial plane. A meaningful conclusion was put forward for designing such Dy-based SIMs with high performance.
对一系列具有五角双锥对称性的镧系多金属氧酸盐(POMs),即[Ln(NMP)(PWO)][PWO](NMP为N-甲基吡咯烷酮)中的磁结构相关性进行了详细的实验研究,并结合理论计算。此外,构建了两种具有五角双锥对称性的基于Dy的配合物,以讨论当基态克莱默斯二重态中的磁轴沿轴向取向或位于赤道平面时,理论能垒与轴向Dy-O键长的依赖性。为设计高性能的此类基于Dy的单离子磁体(SIMs)提出了有意义的结论。
