4-Aminobenzoic acid–1,2-bis(4-pyridyl)ethane (2/1)

Abstract

In the title compound, C12H12N2·2C7H7NO2, the 4-aminobenzoic acid molecules are linked by O—H...N hydrogen bonds to 1,2-bis(4-pyridyl)ethane, forming linear hydrogen bonded chains parallel to [2overline{1}1]. The structure exhibits a hydrogen-bonding network involving COOH...N(pyridyl) and amine and carboxylic N—H... O interactions. In addition, π–π stacking interactions [centroid–centroid distance = 3.8622 (14) Å] are also present.
