چکیده
In the title compound, C(12)H(10)N(4)·C(8)H(6)O(4), 1,4-bis-(imidazol-1-yl)benzene and terephthalic acid mol-ecules are joined via strong O-H⋯N hydrogen bonds to form infinite zigzag chains. Both mol-ecules are located on crystallographic inversion centers. The O-H⋯N hydrogen-bonded chains are assembled into two-dimensional layers through weak C-H⋯O and strong π-π stacking inter-actions [centroid-centroid distance = 3.818 (2) Å], leading to the formation of a three-dimensional supra-molecular structure.
