Lanthanide (Ln) high-nuclearity clusters express charming structures and extensive potential applications; nevertheless, the progress of successfully obtaining Ln clusters is still untoward. Herein, two fascinating and classical 60-metal configurations were obtained based on mixed-lanthanide and solvothermal conditions, namely [Ln₆₀(CO₃)₈(μ₃-OH)₉₆(H₂dmp)₂₄(Hdmp)₁₂] Br₁₂(NO₃)₈(CH₃OH)_x(H₂O)_y (abbreviated as mixed-Ln₆₀; for compound 1, Ln₆₀ = Eu_52.7Gd_7.3, x = 8, y = 43; for compound 2, Ln₆₀ = Eu_52.2Tb_7.8, x = 15, y = 30; H₂dmp⁻ or Hdmp²⁻ = 2,2-dimethylol propionic acid = L). The crystallographic study showed that the 60-metal core of compounds 1 and 2 are protected by a single type of organic ligand without any extra auxiliary ligand to complete the coordination sphere, which are the first to be reported in the containing Ln high-nuclearity clusters. Besides, the synthesis of 1 and 2 provides a practical way to obtain more analogues of Ln high-nuclearity clusters, featuring the original structure of the metal frame, which is expected to break the ionic radius limitation in the synthesis.

单配体保护的Eu60-nGd（Tb）n簇：扩展镧系元素聚集的合理新方法

镧系（Ln）高核簇具有迷人的结构和广泛的潜在应用。然而，成功获得Ln簇的进展仍然不理想。在本文中，基于混合的镧系元素和溶剂热条件，即[LN得到两个迷人和古典60金属结构₆₀（CO ₃）₈（μ ₃ -OH）₉₆（H ₂ DMP）₂₄（HDMP）₁₂ ]溴₁₂（NO ₃）₈（CH ₃ OH）_x（H ₂ O）_y（缩写为Mixed-Ln ₆₀; 对于化合物1，Ln ₆₀＝Eu _52.7 Gd _7.3，x＝ 8，y＝ 43。对于化合物2，Ln ₆₀＝Eu _52.2 Tb _7.8，x＝ 15，y＝ 30。ħ ₂ DMP ^-或HDMP ^2- = 2,2-二羟甲基丙酸=大号）。晶体学研究表明，化合物1和2的60金属核被单一类型的有机配体保护，没有任何额外的辅助配体来完成配位球，这是在含Ln高核簇中首次报道的。此外，合成1和2提供了一种实用的方法来获得更多的Ln高核簇类似物，其具有金属框架的原始结构，有望突破合成中的离子半径限制。
