Abstract
In the title compound, C(12)H(12)N(2)·2C(7)H(7)NO(2), the 4-amino-benzoic acid mol-ecules are linked by O-H⋯N hydrogen bonds to 1,2-bis-(4-pyrid-yl)ethane, forming linear hydrogen bonded chains parallel to [21]. The structure exhibits a hydrogen-bonding network involving COOH⋯N(pyrid-yl) and amine and carb-oxy-lic N-H⋯ O inter-actions. In addition, π-π stacking inter-actions [centroid-centroid distance = 3.8622 (14) Å] are also present.
摘要
在标题化合物C₁₂H₁₂N₂·2C₇H₇NO₂中，4-氨基苯甲酸分子通过O—H⋯N氢键与1,2-双（4-吡啶基）乙烷相连，形成平行于[21]的线性氢键链。该结构呈现出一个涉及COOH⋯N（吡啶基）以及胺和羧基的N—H⋯O相互作用的氢键网络。此外，还存在π-π堆积相互作用[质心-质心距离 = 3.8622 (14) Å]。
