Flexible donor ligands like 1,2-bis(3-pyridyl)ethyne or 1,4-bis(3-pyridyl)-1,3-butadiyne self-assemble into discrete supramolecules instead of infinite networks upon combination with organoplatinum 90, 120, and 180 degree acceptor units. These systems are unique examples of versatile pyridine donors adjusting their bonding directionality to accommodate rigid platinum acceptors in the formation of closed macrocycles.
像1,2-双(3-吡啶基)乙炔或1,4-双(3-吡啶基)-1,3-丁二炔这样的柔性供体配体，与有机铂90度、120度和180度受体单元结合时，会自组装成离散的超分子，而不是无限网络。这些体系是多功能吡啶供体的独特例子，它们调整其键合方向性以在形成封闭大环时容纳刚性铂受体。
