A rare example of an organometallic terbium single-ion magnet is reported. A Tb -[1]ferrocenophane complex displays a larger barrier to magnetization reversal than its isostructural Dy analogue, which is reminiscent of trends observed for lanthanide-bis-phthalocyanine complexes. Detailed ab initio calculations support the experimental observations and suggest a significantly larger ground-state stabilization for the non-Kramers ion Tb in the Tb complex than for the Kramers-ion Dy in the Dy complex.
报道了一例罕见的有机金属铽单离子磁体。一种铽-二茂铁配合物与其同结构的镝类似物相比，显示出更大的磁化反转能垒，这让人想起在镧系双酞菁配合物中观察到的趋势。详细的从头算计算支持了实验观察结果，并表明铽配合物中的非克莱默斯离子铽的基态稳定性比镝配合物中的克莱默斯离子镝显著更大。
