Two new molecular magnets, the dodecanuclear manganese complexes of the type [Mn O (O CR) (H O) ] (known for R = CH , new for R = o-ClC H , o-BrC H ) have contributed to a better quantum mechanical understanding of single-molecule magnets. For instance, appreciable differences in the steps seen in the magnetization hysteresis loops of these high-spin clusters are attributed to changes in the rates of magnetization tunneling from one complex to another.
两种新型分子磁体，即[MnO(OCR)(H₂O)]类型的十二核锰配合物（R = CH₃时已知，R = o-ClC₆H₄、o-BrC₆H₄时为新发现），有助于从量子力学角度更好地理解单分子磁体。例如，这些高自旋簇的磁化滞后回线中出现的明显差异归因于从一种配合物到另一种配合物的磁化隧穿速率的变化。
