The asymmetric unit of title compound, C7H6N4·C6H6O2, contains one 5-(1H-imidazol-1-yl)pyrimidine molecule and two half benzene-1,4-diol molecules; the benzene-1,4-diol molecules are located on individual inversion centers. In the pyrimidine molecule, the imidazole ring is twisted with respect to the pyrimidine ring at a dihedral angle of 25.73 (7)°. In the crystal, O—H...N hydrogen bonds link the molecules to form supramolecular chains. π–π stacking is also observed in the crystal, the centroid–centroid distance between parallel imdazole rings being 3.5543 (16) Å.
