Sažetak
Amines generally have been found to act as halogen bond acceptors. An overview of currently available literature onhalogen-bonded cocrystals of aromatic diamines (which do not have other functional groups) with perhalogenated compounds reveals that only one structure has been reported which contains I···Naminohalogen bonds. In order to investigate the halogen bonding proclivity of aromatic diamines, two selected diamines, benzidine (bnzd) and o-tolidine (otol), were cocrystallized with perhalogenated halogen bond donors: 1, 3-, 1, 4-diiodotetrafluorobenzene (13tfib, 14tfib) and 1, 3, 5- trifluorotriodobenzene (135tfib). Molecular and crystal structures of all four cocrystals have been determined by single crystals X-ray diffraction. All cocrystals exhibited short I···N halogen bonds (between 2, 9 Å and 3, 1 Å), whereas the angle φ(C–I···N) varied between 175, 4° and 176, 9°. In (otol)(14tfib), the molecules are predominantly connected by I···N halogen bonds, while in other three cocrystals, (bnzd)(13tfib)2, (otol)(135tfib)2and (bnzd)(135tfib)4, also are present I∙∙∙π interactions. Furthermore, I···I contacts were present in cocrystals (bnzd) (135tfib)4and (otol)(135tfib)2and, albeit the distances between two iodine atoms were large (between 3.8 and 3.9 Å), the bond angles are in order for type II interhalogen contact.
