Single-molecule magnets (SMMs) show wide potential applications in the field of ultrahigh-density storage materials, quantum computing, spintronics, and so on. Lanthanide (Ln) SMMs, as an important category of SMMs, open up a promising prospect due to their large magnetic moments and huge magnetic anisotropy. However, the construction of high performance for Ln SMMs remains an enormous challenge. Although remarkable advances are focused on the topic of Ln SMMs, the research on Ln SMMs with different nuclear numbers is still deficient. Therefore, this review summarizes the design strategies for the construction of Ln SMMs, as well as the metal skeleton types. Furthermore, we collect reported Ln SMMs with mononuclearity, dinuclearity, and multinuclearity (three or more Ln spin centers) and the SMM properties including energy barrier (U ) and pre-exponential factor (τ ) are described. Finally, Ln SMMs with low-nuclearity SMMs, especially for single-ion magnets (SIMs), are highlighted to understand the correlations between structures and magnetic behavior of the detail SMM properties are described. We expect the review can shed light on the future developments of high-performance Ln SMMs.
单分子磁体（SMMs）在超高密度存储材料、量子计算、自旋电子学等领域展现出广泛的潜在应用。镧系（Ln）单分子磁体作为单分子磁体的一个重要类别，因其大磁矩和巨大的磁各向异性而展现出广阔的前景。然而，构建高性能的镧系单分子磁体仍然是一个巨大的挑战。尽管在镧系单分子磁体这一主题上已经取得了显著进展，但对不同核数的镧系单分子磁体的研究仍然不足。因此，本综述总结了构建镧系单分子磁体的设计策略以及金属骨架类型。此外，我们收集了已报道的具有单核、双核和多核（三个或更多Ln自旋中心）的镧系单分子磁体，并描述了其单分子磁体性质，包括能垒（U）和指前因子（τ）。最后，重点介绍了低核数的镧系单分子磁体，特别是单离子磁体（SIMs），以了解其结构与详细单分子磁体性质的磁行为之间的相关性。我们期望本综述能够为高性能镧系单分子磁体的未来发展提供启示。
