Infinite and discrete halogen bonded assemblies based upon 1,2-bis(iodoethynyl)benzene
The ability to form both infinite and discrete co-crystals based upon 1,2-bis(iodoethynyl)benzene as a halogen bond donor has been realized. The various co-crystals are held together by I⋯N halogen bonds from the donor to either a symmetrical bipyridine or an unsymmetrical monopyridine-based acceptor producing a one-dimensional wave-like polymer or discrete assembly, respectively.
