Designed cocrystals based on the pyridine-iodoalkyne halogen bond.
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.
