“…The central [Dy 3 ] forms a triangular structure (Figure S9) bridged by a μ 3 -OH – and three μ 2 -OH – with the Dy–O–Dy bond angles of 105.40(18)° and 114.86(19)°, respectively. Similar Dy 3 triangle complexes have also been reported. ,,,− Each Dy(III) ion is seven-coordinate (Figure S10) and is surrounded by two phenol oxygen atoms of the L 2– ligand from [Zn II Cl(L)] − , three bridging oxygen atoms of OH – , one ethanol oxygen atom, and one chloride ion. The bond lengths of Dy–Cl are all 2.7535(16) Å, longer than the six Dy–O coordination bond lengths in the range of 2.220(3)–2.445(5) Å.…”

Multifunctional single-molecule magnets (SMMs) have sparked great interest, but chiral SMMs obtained via spontaneous resolution are rarely reported. We synthesized a series of chiral trinuclear hepta-coordinate lanthanide complexes [ZnII 3LnIII 3] (1 for Dy, 2 for Tb, 3 for Gd, and 4 for Dy0.07Y0.93) using the achiral flexible ligand H2L (2,2′-[1,2-ethanediylbis[(ethylimino)methylene]]bis[3,5-dimethylphenol]). The complexes crystallize in the chiral P63 group space, and two enantiomers of different chirality are spontaneously resolved. Three [Zn(L)Cl]− anions utilize the two phenoxy oxygen atoms of each L2– to coordinate with three lanthanide ions, respectively, and the three hepta-coordinate D 5h lanthanide ions are arranged in a triangle. The chirality comes from the propeller arrangement of the peripheral three bidentate chelate L2– ligands like octahedral [M(AA)3] n+/– (M = transition metal ions; AA = bidentate chelate ligands, e.g., 2,2′-bipyridine, 1,10-phenathroline, ethylenediamine, acac– or oxalate). Complex 1 exhibits an AC susceptibility signal and is frequency-dependent, which is typical of SMMs. Complex 4, doped with a large amount of diamagnetic Y(III) in Dy(III), exhibits U eff = 48.3 K and τ0 = 4.4 × 10–8 s in experiments. Complex 2 shows circularly polarized luminescence and apparent photoluminescence, typical of the f–f transitions of Tb(III).

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 con-struction 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 eff ) and pre-exponential factor (τ 0 ) 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 highperformance Ln SMMs.
