The title compound C6H4(C7H5N2)2 was prepared by the condensation of o-phenyl- enediamine with o-phthalic acid and characterized by elemental analysis, IR, UV and 1H NMR spectra, and its structure was determined by single-crystal X-ray diffraction. The crystal belongs to orthorhombic system, space group Pbcn with a = 17.928(8), b = 8.828(4), c = 9.752(4)(A), Z = 4, V = 1543.4(12) (A)3, Dc = 1.336 g/cm3, Mr = 310.35, λ(MoKα) = 0.71073 (A), μ = 0.082 mm-1, F(000) = 648, R = 0.0405 and wR = 0.1092. A total of 1693 unique reflections were collected, of which 1319 with I > 2σ(I) were observed. It is shown that the compound molecule belongs to C2 point group. A one-dimensional chain structure was formed by the intermolecular hydrogen bonds (N(2)-H…N(1)).
