In the self-assembly of Pd(II) ions and two different, but similarly shaped, ligands (1 and 2), neither random mixing nor self-sorting of the two ligands into two unmixed structures was observed. Instead a mixed, yet sorted, Pd12 (1)12 (2)12 cantellated tetrahedron (and its pseudoisomer) was selectively formed, thus revealing a fine example of intramolecular self-sorting. A case study showed that a homothetic ratio of >2 is necessary to observe cantellated tetrahedra.
在 Pd(II) 离子和两个不同但形状相似的配体(1 和 2)的自组装中,没有观察到两种配体随机混合或自行分成两种不混合的结构。相反,选择形成了一种混合但有序的 Pd12(1)12(2)12 截角四面体(及其假异构体),从而揭示了分子内自分类的一个很好的例子。案例研究表明,需要等比大于 2 才能观察到截角四面体。
