| 英文摘要 | The title complex [zn(mu-o2cch=chco2)(c3h4n2)(h2o)](n) was prepared by the reaction of zinc carbonate with maleic acid and imidazole in an aqueous-alcohol solution at 333 k, and its crystal structure has been solved by single-crystal x-ray diffraction. the complex crystallizes in the monoclinic system, space group pc with a = 5.3858(7), b = 22.685(3), c 7.6782(1) angstrom, beta = 92.261(2)degrees, v = 937.4(2) angstrom(3), z = 1, c14h16n4o10zn2, m-r = 531.05, d-c = 1.882 g/cm(3), mu = 2.623 mm(-1), f(000) = 532, the final r = 0.0372 and wr = 0.0930 for 1926 observed reflections with i>2sigma(i). the central zinc atom is five-coordinated in a distorted square pyramidal environment to three oxygen atoms of two different maleate ligands, a nitrogen atom of the imidazole ligand and an oxygen atom of water. in the complex two carboxylate groups of the maleate ligands have two coordination modes. one acts as a bidentate chelate ligand and the other a monoatomic monodentate ligand to bridge two zinc centers. as a result, 1-d infinite polymeric chains are formed, which are linked together by pairs of o-(ho)-o-... hydrogen bonds between the coordination water oh groups and carboxylate oxygen atoms to construct a 2-d layered polymer, and the layer structure is stabilized by pi-pi stacking of the imidozel ligands. |
