Sažetak
The study of halogen bond in multicomponent systems is one of the most developing areas in crystal engineering and supramolecular chemistry [1]. Alongside the halogen bond, an entire family of related σ-hole interactions, including pnicogen atoms have been described [2]. One of the functional groups that has potential to form both halogen and pnicogen bonds is nitro group [3, 4]. In this research, cocrystals of imines derived from 2- nitrobenzaldehyde (nba) and 4-X-aniline (Xan, X = Cl, Br, I) with 1, 3- diiodotetrafluorobenzene (13tfib) and 1, 3, 5- triiodotrifluorobenzene (135tfib) were synthesized by cocrystallization from solution and mechanochemically. X-ray structural analysis revealed a successful synthesis of six cocrystals exhibiting 1:1 stoichiometry. In all cocrystals, halogen bond donors and imines are connected via Nimine∙∙∙I halogen bonds, while in five cocrystals imines are additionally connected via Nnitro∙∙∙Onitro pnicogen bonds, and nitro group interactions.
