A halogen-bonded eight-fold interpenetrated diamondoid net was constructed employing a node generated in the solid state. Specifically, co-crystallization of a tetrahedral-like tecton, rctt-tetrakis(4-pyridyl)cyclobutane (4,4′-TPCB), combined with a rigid halogen-bond donor, 1,4-diiodoperchlorobenzene, achieved a diamondoid architecture. In the co-crystal, 4,4′-TPCB is found to form three types of linkages based on one cis- and two trans-orientations enabled by the intrinsic rctt-stereochemisty of the central cyclobutane ring. Thus, 4,4′-TPCB is able to adapt to the constraints of the diamondoid net owing to the flexibility of the pendant 4-pyridyl groups.

由卤素键维持的类金刚石网：采用环丁烷生成四面体结构

使用固态产生的结点构造卤素键合的八倍互穿的类金刚石网。具体而言，将四面体状构造体rctt-四（4-吡啶基）环丁烷（4,4'-TPCB）与刚性卤素键供体1,4-二碘过氯苯结合进行共结晶，即可获得类金刚石结构。在共晶体中，发现4,4'-TPCB基于中央环丁烷环固有的rctt-立体化学实现的一种顺式和两种反式取向形成三种类型的键合。因此，由于4-吡啶基侧基的柔性，因此4,4'-TPCB能够适应类金刚石网的约束。
