Abstract

In the title compound, C5H5ClN2·C7H6O2, the carboxyl group of the benzoic acid molecule is twisted away from the attached ring by 14.22 (7)°. In the crystal, the 2-amino-5-chloropyridine molecules interact with the carboxyl groups of benzoic acid molecules through N—H⋯O and O—H⋯N hydrogen bonds, forming cyclic R 2 2(8) hydrogen-bonded motifs, and linking the molecules into chains parallel to the [001] direction. Neighbouring 2-amino-5-chloropyridine molecules are also centrosymmetrically paired through C—H⋯Cl hydrogen bonds, forming another R 2 2(8) motif. The crystal structure is further stabilized by weak C—H⋯O hydrogen bonds.
