Sažetak
Amino groups are commonly understood as electron donating, which is reflected through their use as hydrogen and halogen bond acceptors in crystal engineering [1-4], However, aromatic diamines which do not have other functional groups have only recently been employed as halogen bond acceptors for construction of cocrystals with perhalogenated compounds based on I⋯Namino halogen bonds [5J. Inspired by scarcity of such systems to date, four cocrystals were prepared with benzidine (bnzd) and o-tolidine (otol) as halogen bond acceptors and 1, 3-, 1, 4- diiodotetrafluorobenzene (13tfib, 14tfib) and 1, 3, 5-trifluorotriiodobenzene (135tfib) as halogen bond donors. Cocrystals were obtained as single crystals by crystallization in ethanol and were characterized 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 (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)2 and (bnzd)(135tfib)4, also are present I⋯interactions. Furthermore, FT contacts were present in cocrystals (bnzd) (135tfib)4 and (otol)(135tfib)2 and, albeit the distances between two iodine atoms were large (between 3.8 and 3.9 A), the bond angles are in order for type II interhalogen contact ((C−I⋯ N) ≈ 105°).
