The supramolecular organization in six solid assemblies involving iodo- and bromoperfluoroarene derivatives is described. Single crystal X-ray analyses show that the formation of the supramolecular architectures is controlled by I−⋯Br–ArF, I−⋯I–ArF, Br−⋯I–ArF, and Cl−⋯I–ArF halogen bondings thus proving the X−⋯X′–ArF supramolecular synthon, where X can be the same as or different from X′, is particularly
