2,6-二甲酰吡啶与多种胺和Pd（II）离子反应生成多种金属超分子物质，其中Pd（II）离子模板形成三齿双（亚）吡啶配体。这些物种包括单核复合物以及[2+2]和[3+3]大环。含有吡啶的大环旋盖配体的添加允许拓扑复杂性的出现，从而能够直接制备包括[2]链烷，[2]轮烷和双螺纹[3]轮烷的结构。
The reaction of 2,6-diformylpyridine with diverse amines and Pd(II) ions gave rise to a variety of metallosupramolecular species, in which the Pd(II) ion is observed to template a tridentate bis(imino)pyridine ligand. These species included a mononuclear complex as well as [2+2] and [3+3] macrocycles. The addition of pyridine-containing macrocyclic capping ligands allows for topological complexity to arise, thereby enabling the straightforward preparation of structures that include a [2]catenane, a [2]rotaxane, and a doubly threaded [3]rotaxane.
