A new complex, [Zn(L)_2](1), has been hydrothermally prepared by the reaction of ZnSO_4·7H_2O 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) ?, β = 92.889(2)o, V = 1774.4(3) ?~3, Z = 4, C_(20)H_(14)N_4O_4 Zn, M_r = 439.72, D_c = 1.646 g/cm~3, 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.
