By looking at the structures of halogen-bonded infinite chains with two diiodoperfluoroalkanes and a bent bis(pyrid-4′-yl)oxadiazole, Giuseppe Resnati and colleagues have investigated the influence that halogen bond directionality has on supramolecular design. The bent geometry of the pyridyl pendant rings in the structures were found to translate into the angle between the formed halogen bonds, taking precedence over parameters that might affect the crystal packing.
