In the acid molecule of the title complex, C10H8N2·C8H8O3, the acetyl C—C—C—O torsion angle is −32.1 (3)°, and in the molecule of the base, the dihedral angle between the two pyridine rings is 23.41 (10)°. In the crystal structure, intermolecular O—H⋯N hydrogen bonds link the acid and the base molecules into a one-dimensional triple-helix framework extended along the b axis.
