由20个Cu离子（1）组成的离散纳米球形二十金属簇（icosametallic cluster）从简易合成中自组装。通过选择配体来调整合成，产生了具有完整的二十烷酸核心和改善的稳定性的另一簇（2）。参考1和2的合成，设计并通过单晶X射线衍射，结合元素分析，能量色散X射线，X射线光电子能谱，热重分析和元素图谱表征了含有12个Cu（II）和8个Zn（II）的杂金属簇合物（3）。2和3的磁性测量以及来自2和3的金属氧化物的扫描电子显微镜图像和紫外-可见漫反射测量表明，{Cu 12 M8}的分离是具有工程性质的材料的新合成路线。
A discrete nanospheric icosametallic cluster comprised of 20 Cu ions (1) was self-assembled from facile synthesis. Adjustment of the synthesis by the choice of ligands gave rise to another cluster (2) with an intact icosacupric core and improved stability. Referring to the synthesis of 1 and 2, a heterometallic cluster (3), which contains 12 Cu(II) and 8 Zn(II), was designed and characterized by single-crystal X-ray diffraction, combined with elemental analysis, energy-dispersive X-ray, X-ray photoelectron spectroscopy, thermogravimetric analysis, and element mapping. The magnetic measurements of 2 and 3 and the scanning electron microscopy images and UV-visible diffuse-reflectance measurements of metal oxides from 2 and 3 indicate that isolation of {Cu12M8} is a new synthetic route to materials with engineered properties.
