Crystal structure of 4-aminobenzoic acid-4-methylpyridine (1/1)

Abstract

In the title 1:1 adduct, C6H7N·C7H7NO2, the carboxylic acid group is twisted at an angle of 4.32 (18)° with respect to the attached benzene ring. In the crystal, the carboxylic acid group is linked to the pyridine ring by an O - H⋯N hydrogen bond, forming a dimer. The dimers are linked by N - H⋯O hydrogen bonds, generating (010) sheets.
