Benzene-1,4-diol-5-(1H-imidazol-1-yl)pyrimidine (1/1)

The asymmetric unit of title compound, C(7)H(6)N(4)center dot C(6)H(6)O(2), 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)degrees. In the crystal, O-H center dot center dot center dot N hydrogen bonds link the molecules to form supramolecular chains. pi-pi stacking is also observed in the crystal, the centroid-centroid distance between parallel imdazole rings being 3.5543 (16) angstrom.
