摘要
A three-dimensional cobalt coordination polymer [Co（IMPAA）2]n（1, HIMPAA =（2E）-3-[4-（1H-imidazol-1-ylmethyl）phenyl]acrylic acid） was synthesized with ozagrel and structurally characterized by element analysis, IR, PXRD, TGA and X-ray diffraction. Complex 1 is of monoclinic system, space group P21 with a = 5.136（4）, b = 25.577（19）, c = 8.174（6） A, V = 1078.6（14） A3, Mr = 513.41, Z = 2, Dc = 1.581 g/cm3, F（000） = 686, μ = 0.840 mm-1, S = 1.119, Rint = 0.0637 and w R = 0.1456. In complex 1, four IMPAA- and four Co（II） ions form a S-shaped 52-membered macrocycle [Co4（IMPAA）4]4＋. Two carboxlate oxygen atoms link the macrocycles to form a one-dimensional chain. IMPAA- ligands bridge one-dimensional chains to yield a novel three-dimensional metal-organic framework（MOFs）. The complex is stable up to 350 ℃.
