Nanoscale inorganic wheel-shaped structures are one of the most striking types of molecular aggregations. Here, we report the synthesis of a gigantic lanthanide wheel cluster containing 140 Gd atoms. As the largest lanthanide cluster reported thus far, {Gd} features an attractive wheel-like structure with 10-fold symmetry. The nanoscopic molecular wheel possesses the largest diameter of 6.0 nm and displays high stability in solution, which allows direct visualization by scanning transmission electron microscopy. The newly discovered lanthanide {Gd} cluster represents a new member of the molecular wheel family.
纳米级无机轮状结构是最引人注目的分子聚集类型之一。在这里，我们报告了一种巨大的镧系轮簇的合成，其中包含 140 个 Gd 原子。作为迄今为止报道的最大镧系簇，{Gd}具有吸引人的十重对称轮状结构。这种纳米级分子轮具有最大直径为 6.0nm，并在溶液中表现出高稳定性，这使得可以通过扫描透射电子显微镜直接进行可视化。新发现的镧系元素{Gd}簇代表了分子轮家族的一个新成员。
