π-hole···π and π–π interactions, cocrystals of nonplanar 4-arylated-2,2′-bipyridine (ArB) derivatives with 1,4-diiodo-tetrafluorobenzene (D) were generated which exhibit a promising columnar/lamellar packing arrangement. Hirshfeld surface, quantum theory of atoms in molecules, and electrostatic potential surface analyses were employed to examine the weak intermolecular interactions governing the packing
受强方向性C–I··N非共价卤素键,π-孔···π和π–π相互作用的刺激,非平面4-芳基化2,2'-联吡啶(ArB)衍生物与1,4-的共晶体生成的二碘四氟苯(D)具有良好的柱状/片状堆积结构。利用Hirshfeld表面,分子中的原子量子理论和静电势表面分析来研究弱分子间相互作用,这些相互作用决定了ArB晶体以及与D(ArB·D)对应的共晶体的堆积排列。4-苯基-2,2'-联吡啶(PhB)和4-(萘-1-基)-2,2'-联吡啶(NaB)与D [PhB·D1,PhB·D2,(NaB)2 ·D 2.5和(NaB)3 ·D 2]展示了交替出现ArB和D单元的C–I···N定向无穷一维链。相反,C–I··N相互作用指导了在与D(PhenB·D 0.5)共聚的4-(菲基-9-基)-2,2'-联吡啶共晶体中的分子配合物的形成。通过2,2'-联吡啶和D的C–I··N相互作用的成功实施,可以将平面多芳烃中的
