摘要: 在3d-4f类型中的单分子磁体里，铜通常以二价的形式存在，并且它的特征电子构型为3d⁹，因此被认为是顺磁中心。在八面体配位环境中，Cu^II的d层轨道分裂成了t_2g⁶e_g³，这就导致了Cu^II中会出现Jahn-Teller效应。结合这些特性，Cu^II会表现出中等的磁各向异性，因此通常被认为是各向同性离子。然而，由于其灵活的配位性，以及它会与4f金属形成强铁磁耦合的能力，Cu-Ln SMMs仍然是研究的焦点。

Abstract: In 3d-4f SMMs, copper is typically present in the Cu^Ⅱ form, characterized by 3d⁹ electron configuration, and is thus commonly regarded as paramagnetic center. In octahedral coordination environment, the d orbitals of Cu^Ⅱ split into t_2g⁶e_g³, leading to the occurrence of the Jahn-Teller effect in Cu^Ⅱ. Combining these characteristics, Cu^Ⅱ exhibits moderate magnetic anisotropy, and thus is often regarded as isotropic ion. However, due to its flexible coordination, along with its ability to form strong ferromagnetic couplings with 4f metals, Cu-Ln SMMs have remained the focal point of research.
