title: Crystal structure of 4-amino-benzoic acid-4-methyl-pyridine (1/1).
abstract: In the title 1:1 adduct, C6H7N·C7H7NO2, the carb-oxy-lic acid group is twisted at an angle of 4.32 (18)° with respect to the attached benzene ring. In the crystal, the carb-oxy-lic 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.
