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) ?, V = 1078.6(14) ?3, 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 ℃.
