摘　　要：The reaction of 1,2-benzenedicarboxylic acid（H2L） with Zn（NO）3·6H2O and selfdesigned 1,2-bis（imidazol-1-ylmethyl）-benzene）（2-bimb） in DMA/H2 O results in the forming of double chains ZnⅡ complex, {[Zn2.5（L）2（bimb）（H2O）]·H2O}n（1）, which has been characterized by TGA, PXRD and single-crystal X-ray diffraction. Compound 1 crystalizes in monoclinic, space group P1 with a = 11.4030（3）, b = 11.9722（3）, c = 13.5702（4） A, α = 89.903（3）, β = 80.692（2）, γ = 63.999（3）o, C64H56N8O20Zn5, Mr = 1584.01, V = 1638.15（9） A3, Z = 1, Dc = 1.606 g·cm-3, μ = 1.885 mm-1, F（000） = 806., 2.07θ25°, λ（Mo Kα） = 0.71073 A, T = 293（2） K, the final R = 0.0439, wR = 0.01393 and S = 1.057. X-ray diffraction analysis reveals that complex 1 possesses a 2D double-chain structure. In addition, the solid state luminescent property of complex 1, H2 L, and 2-bimb at room temperature are also investigated.The reaction of 1,2-benzenedicarboxylic acid（H2L） with Zn（NO）3·6H2O and selfdesigned 1,2-bis（imidazol-1-ylmethyl）-benzene）（2-bimb） in DMA/H2 O results in the forming of double chains ZnⅡ complex, {[Zn2.5（L）2（bimb）（H2O）]·H2O}n（1）, which has been characterized by TGA, PXRD and single-crystal X-ray diffraction.
