摘　　要：The title coordination polymer, [Co（1,4-ndc）（L）（H2O）]n 1 （1,4-H2ndc = 1,4-na- phthalenedicarboxylic acid and L =1-（5-（1H-imidazol- 1-yl）pentyl）- 1H-imidazole） has been hydrothermally synthesized and characterized by IR and single-crystal X-ray diffraction. It crystallizes in monoclinic, space group P21/n with a = 12.4333（12）, b = 13.2963（13）, c = 13.4678（13）A, α =β = 90°, y =107.302（2）°, V= 2125.7（4）A^3, Z = 4, CoC22H22N4O5, Mr = 481.37, De = 1.504 g/cm^3, F（000） = 996, μ（MoKa） = 0.850 mm^-1, R = 0.0472 and wR = 0.0984. Compound 1 exhibits a two-dimensional layer structure. The O-H...O and C-H...O hydrogen bonds stabilize the structure of 1.The title coordination polymer, [Co（1,4-ndc）（L）（H2O）]n 1 （1,4-H2ndc = 1,4-na- phthalenedicarboxylic acid and L =1-（5-（1H-imidazol- 1-yl）pentyl）- 1H-imidazole） has been hydrothermally synthesized and characterized by IR and single-crystal X-ray diffraction.
