同结构的三核混合金属[Fe(5)(III)Ln(8)(III)](Ln=Pr，Nd，Gd)聚集体是迄今报道的最大的[Fe-Ln]团簇，磁性表明[Fe5Pr8]和[Fe5Nd8]具有亚铁磁性排列，而[Fe5Gd8]铁磁相互作用占主导地位，导致较大的自旋基态。
The isostructural tridecanuclear mixed-metal [Fe(5)(III)Ln(8)(III)] (Ln = Pr, Nd, Gd) aggregates are the largest [Fe-Ln] clusters reported to date and the magnetic properties suggest a ferrimagnetic arrangement in [Fe5Pr8] and [Fe5Nd8], whereas for [Fe5Gd8] ferromagnetic interactions are dominant leading to a large spin ground state.
