摘　　要：A new complex, [Zn（L）2]（1）, has been hydrothermally prepared by the reaction of ZnSO4·7H2O with 2-（1H-imidazol-4-yl）benzoic acid（HL） incorporating 4-imidazolyl and carboxylate functional groups, and characterized by single-crystal X-ray diffraction, elemental analysis, IR spectroscopy and powder X-ray diffraction（PXRD）. Complex 1 crystallizes in monoclinic, space group C2/c with a = 9.8349（9）, b = 7.4947（7）, c = 24.104（2） A, β = 92.889（2）o, V = 1774.4（3）A3, Z = 4, C（20）H（14）N4O4 Zn, Mr = 439.72, Dc = 1.646 g/cm3, μ = 1.422 mm-1, S = 1.003, F（000） = 896, the final R = 0.0395 and wR = 0.0874 for 11386 observed reflections（I 〉 2σ（I））. Single-crystal X-ray structural analysis reveals that complex 1 features a two-dimensional（2D） framework with 6~3-hcb topology. Moreover, the photoluminescent property of 1 was also discussed.A new complex, [Zn（L）2]（1）, has been hydrothermally prepared by the reaction of ZnSO4·7H2O with 2-（1H-imidazol-4-yl）benzoic acid（HL） incorporating 4-imidazolyl and carboxylate functional groups, and characterized by single-crystal X-ray diffraction, elemental analysis, IR spectroscopy and powder X-ray diffraction（PXRD）.
