Two unprecedented wheel-shaped nanoscale clusters {Co(II)16Ln(III)24} (Ln = Dy and Gd), with a diameter and a thickness of 3.0 nm and 2.0 nm, respectively, were obtained from the self-assembly of Co(NO3)2, Ln(NO3)3 and a pyridyl-functionalized β-diketone ligand. Notably, the gadolinium species exhibited a relatively large magnetocaloric effect.
两个前所未有的轮状纳米级簇{Co(II)16Ln(III)24}（Ln = Dy 和 Gd），分别具有 3.0nm 的直径和 2.0nm 的厚度，由 Co(NO3)2、Ln(NO3)3 和一个吡啶基功能化的β-二酮配体自组装而成。值得注意的是，钆物种表现出较大的磁热效应。
