The formation and crystal structure of a zigzag mol-ecular network held together by I⋯N halogen bonds is reported. In particular, the halogen-bond donor is 1,2-di-iodo-perchloro-benzene ( ) while the acceptor is a head-to-tail photoproduct, namely -1,3-bis-(pyridin-4-yl)-2,4-di-phenyl-cyclo-butane ( ). In this co-crystal ( )·( ), the donor acts as a bent two-connected node while the acceptor behaves as a linear linker to form the extended solid. Neighbouring chains pack in a tongue-and-groove-like pattern that engage in various Cl⋯π inter-actions to both the phenyl and pyridyl rings resulting in a supra-molecular two-dimensional sheet.
报道了一种由I⋯N卤键维系的锯齿形分子网络的形成及其晶体结构。具体而言，卤键供体是1,2 - 二碘全氯苯（ ），而受体是一种头对头光产物，即 - 1,3 - 双（吡啶 - 4 - 基）- 2,4 - 二苯基环丁烷（ ）。在这种共晶体（ ）·（ ）中，供体作为弯曲的双连接节点，而受体作为线性连接体形成扩展的固体。相邻链以舌槽状模式堆积，与苯环和吡啶环都发生各种Cl⋯π相互作用，从而形成超分子二维片层。
