| 摘 要： | A new coordination polymer Ni（L）（m-bix）（H2O）]n （1, H2L = 5-iodo-isophthalic acid, m-bix=1,3-bis（imidazol-1-ylmethyl）-benzene） has been synthesized by the hydrothermal method and characterized by IR, elemental analysis, powder XRD and single-crystal X-ray analysis. The crystal is of triclinic, space group Pī with a = 9.1638（3）, b = 10.2319（3）, c = 13.2463（4） ？, α = 80.1710（10）, β = 83.671（2）, γ = 70.3790（10）o,C22H19NiIN4O5, Mr = 605.02, V = 1150.85（6） ？3, Dc = 1.746 g/cm3, F（000） = 600, μ = 2.225 mm-1, S = 1.045 and Z = 2. The final R = 0.0388 and wR = 0.1257 for 5089 observed reflections with I 〉 2σ（I）. In the title complex, the M and P layers are arranged alternately to give a double-layer structure by the symmetry related hydrogen bonds, and these double-layers are further joined together to achieve a 2D supramolecular architecture through I···π interaction involving iodine atoms and imidazole rings. The thermal stability of the title complex was studied by thermal gravimetric （TG） and differential thermal analysis （DTA）.
