Herein, a series of light lanthanide-based complexes, Ln(fdh)₃(bpy) (Ln = Ce^III, Pr^III, and Nd^III and fdh = 1,1,1-fluoro-5,5-dimethyl-hexa-2,4-dione, bpy = 2,2′-bipyridine), were synthesized and characterized. The angle-resolved magnetometry studies reveal that the three complexes have Ising-type anisotropy, and the magnetic easy axes orient along the negative charge dense direction in the crystal field. The results were consistent with the ab initio calculations. This research demonstrates that the crystal field electron density distribution determines the anisotropy of light lanthanides.

轻镧系元素络合物的磁各向异性研究†

在此，一系列基于镧系元素的轻配合物Ln（fdh）₃（bpy）（Ln = Ce ^III，Pr ^III和Nd ^III，fdh = 1,1,1-氟-5,5-二甲基-六-合成并表征了bpy = 2,2'-bipyridine的2,4-二酮。角度分辨磁力计研究表明，这三个配合物具有Ising型各向异性，并且磁易轴沿着晶体场中的负电荷密集方向取向。结果与从头算是一致的。这项研究表明，晶场电子密度分布决定了镧系元素的各向异性。
