Five compounds bearing electron-deficient pentafluorophenyl as well as electron-rich (salicylate or indole) aromatic moieties connected by amide or ester linkages were investigated by X-ray diffraction. In the crystals, various interactions (π–π, lone pair–π) between the different aromatic units are important structure controlling factors in addition to the stronger inter- or intramolecular hydrogen
通过 X 射线衍射研究了五种带有缺电子五氟苯基以及通过酰胺或酯键连接的富电子(水杨酸酯或吲哚)芳族部分的化合物。在晶体中,除了酰胺和酯部分诱导的更强的分子间或分子内氢键之外,不同芳香单元之间的各种相互作用(π-π,孤对-π)是重要的结构控制因素。氢键导致分子结构单元的聚合和大环组装。
