A motif of the supramolecular architecture of соcrystals of 18-crown-6 and polychloropolyfluoro-1,3- phenylenediamines or partially fluorinated 1,3-phenylenediamines (1:1 stoichiometry) is infinite 1D ensembles of alternating components. The mutual coordination of molecules in the ensembles is due to the hydrogen bond between crown ether oxygen atoms and hydrogen atoms of polyfluoroarene amino groups
18-Crown-6 和多氯多氟-1,3-苯二胺或部分氟化的 1,3-苯二胺(1:1 化学计量)的 со 晶体的超分子结构的一个主题是交替组分的无限 1D 集合。系综中分子的相互配位是由于冠醚氧原子与多氟芳烃氨基的氢原子之间的氢键。晶体结构的参数由多卤化芳环中取代基(氯和氟原子)的数量和排列的影响决定。
