Abstract: The formation of two-dimensional halogen-bonded layers of 4,4'-bipyridyl and 1,4-diiodotetrafluorobenzene was observed on a graphite surface at sub-monolayer coverage using synchrotron X-ray diffraction; the use of the diffraction technique enabled, for the first time, the measurement of I center dot center dot center dot N halogen bonding distances in a two-dimensional cocrystal and the identification of the halogen bonding interaction in the monolayer.
