Abstract
Diiodobutadiyne (1) and diiodohexatriyne (2) form cocrystals with bispyridyl oxalamides and ureas, based on the halogen bond between the alkynyl iodine and pyridine nitrogen. In each cocrystal, the oxalamide or urea host forms one-dimensional hydrogen-bonded networks, aligning the diiodopolyyne for potential topochemical polymerization with a repeat distance matching the host repeat.
摘要
二碘丁二炔（1）和二碘己三炔（2）与双吡啶草酰胺和脲形成共晶体，这是基于炔基碘与吡啶氮之间的卤键。在每个共晶体中，草酰胺或脲主体形成一维氢键网络，使二碘多炔排列整齐，以便进行潜在的拓扑化学聚合，其重复距离与主体重复距离相匹配。
