Summary:In the title 1:1 adduct, C6H6N2O·C11H8O2, the amide group is slightly twisted out of the plane of the aromatic ring, with a C—C—C—N torsion angle of 25.11 (19)°, whereas the carboxylic acid group is approximately coplanar with the bicylic ring system, with a C—C—C—O torsion angle of 10.9 (2)°. The amide groups from two isonicotinamide molecules form a dimer via N—H...O hydrogen bonds. In addition, the 2-naphthanoic acid molecule is hydrogen bonded to the pyridine unit of an isonicotinamide molecule via an O—H...N hydrogen bond. This gives rise to a centrosymmetric four-molecule chain, which is cross-linked by further N—H...O hydrogen bonds from the amide group.
