The title compound, （ C13 H14 N2 ）·（ C8H6O4 ）, was hydrothermally synthesized by the reaction of 1,3-his （4-pyridyl） propane, terephthalic acid and deionized water at 413 K. This complex crystallized in triclinic system, space group P1 with a =0. 952 67 （19） nm, b = 1. 192 7 （2） nm, c = 1.695 9（3） nm, a =96.40（3）°,β =98.12（3）°, γ = 101.52（3）°, and Z =2. As characterized by single crystal X-ray diffraction, the asymmetric unit of the title compound is constructed from terephthalic acid （tp） molecules and 1,3-his （4-pyridyl） propane （ bpp ） molecules. The two-dimensional geometry of the title complex is constituted by two types of intermolecular π-π interaction and O--H- N hydrogen bonds.
