As a point of entry to investigate the potential of halogen-bondinginteractions in the construction of functional materials and crystallinemolecular machines, samples of 1,4-bis(iodoethynyl)bicyclo[2.2.2]octane (BIBCO) were synthesized and crystallized. Knowing that halogen-bondinginteractions are common between electron-rich acetylenic carbons and electron-deficient iodines, it was expected that
