The constituents of the title 1:1 co-crystal, C7H6O2·C14H12N2, are connected into dimeric aggregates by a bifurcated O—H⋯N hydrogen bond; the hydroxyl-H atom is hydrogen bonded to the two N atoms of the 2,9-dimethylphenanthroline. The hydrogen-bonded residues are almost orthogonal to each other [dihedral angle = 78.56 (7) °]. In the crystal packing, the aggregates are assembled into layers in the bc plane by π⋯π interactions [ring centroid⋯ring centroid distance = 3.5577 (16) Å] involving the…
