Abstract

In the crystal structure of the title 1:1 adduct, C(12)H(12)N(2)·C(8)H(9)NO(2), the 4-amino-3-methyl-benzoic acid mol-ecules and 1,2-bis-(4-pyrid-yl)ethane mol-ecules are linked by inter-molecular O-H⋯N, N-H⋯O and N-H⋯N hydrogen bonds, forming a two-dimensional supra-molecular network parallel to (001). In the 1,2-bis-(4-pyrid-yl)ethane mol-ecule, the two pyridine rings are twisted to each other by a dihedral angle of 12.12 (8)°. The non-H atoms of the 4-amino-3-methyl-benzoic acid mol-ecule are almost coplanar, the maximum atomic deviation being 0.029 (1) Å. Weak C-H⋯π inter-actions are present in the crystal structure.

摘要

在标题为1:1加合物C(12)H(12)N(2)·C(8)H(9)NO(2)的晶体结构中,4-氨基-3-甲基苯甲酸分子与1,2-双(4-吡啶基)乙烷分子通过分子间的O-H⋯N、N-H⋯O和N-H⋯N氢键相连,形成一个平行于(001)的二维超分子网络。在1,2-双(4-吡啶基)乙烷分子中,两个吡啶环彼此扭转,二面角为12.12 (8)°。4-氨基-3-甲基苯甲酸分子的非H原子几乎共面,最大原子偏差为0.029 (1) Å。晶体结构中存在弱的C-H⋯π相互作用。
