We report the first f-block-ruthenocenophane complexes 1 (Dy) and 2 (Tb) and provide a comparative discussion of their magnetic structure with respect to earlier reported ferrocenophane analogues. While axial elongation of the rare trigonal-prismatic geometry stabilizes the magnetic ground state in the case of Dy and results in a larger barrier to magnetization reversal (U), a decrease in U is observed for the case of Tb .
我们报道了首例f-区-钌茂型配合物1（镝）和2（铽），并就其磁结构与早期报道的二茂铁型类似物进行了对比讨论。虽然在镝的情况下，罕见的三角棱柱几何构型的轴向伸长稳定了磁基态，并导致更大的磁化反转势垒（U），但在铽的情况下观察到U减小。
