  摘要：

  Ten new coordination polymers, namely, [Cd(L)(pbih)(0.5)] (1), [Ni(L)(pbib)]center dot 2H(2)O (2), [Cd-2(L)(2)(pytp)(2)]center dot H2O (3), [Cd(L)(tbpy)] (4), [Ni(L)(pytp)] (5), [Ni(L)(tbpy)]center dot 0.25H(2)O (6), [Cd(L)(biim-6)(0.5)] (7), [Cd(L)(phen)] (8), [Cd-3(L)(3)(H2O)]center dot H2O (9), and [Cd-3(L)(3)(biim-4)(0.5)]center dot 6H(2)O (10), where biim-4 = 1,1'-(1,4-butanediyl)bis (imidazole), biim-6 = 1,1'-(1,6-hexanedidyl)bis(imidazole), pbib = 1,4-bis(imidazol-1-ylmethyl)benzene, phen = 1,10-phenanthroline, pytp = 2-(6'-(pyridin-2 ''-yl)-4'-p-tolylpyridin-2'-yl)pyridine, tbpy = 2-(4'(4 ''-tert-butylphenyl)-6'-(pyridin-2 ''-yl)pyridin-2'-yl)pyridine and H2L = 3-carboxy-1-(4'-(2 ''-carboxy) biphenylmethyl)-2-oxidopyridinium, have been synthesized under hydrothermal conditions. Their structures have been determined by single-crystal X-ray diffraction analyses and further characterized by infrared spectra (IR), elemental analyses, powder X-ray diffraction (PXRD) and thermogravimetric (TG) analyses. Compounds 1 and 2 show layer structures. Neighboring layers are further linked by pi-pi stacking interactions to form 3D supramolecular architectures. Compound 3 consists of two crystallographically different dimers, which are further linked by pi-pi and hydrogen-bonding interactions into a 2D supramolecular architecture. Compounds 4-6 feature chain structures. In 4, neighboring chains are stacked by pi-pi interactions to result in a 2D supramolecular architecture. In 5, the adjacent chains are linked by pi-pi interactions to yield a 3D supramolecular architecture. In 6, neighboring chains are further linked by hydrogen-bonding interactions into a 3D supramolecular architecture. Compound 7 exhibits a 2D 6(3)-hcb network. Neighboring networks are further extended by it-it stacking interactions into a 3D supramolecular architecture. Compound 8 displays a (4,4) sheet. Compound 9 reveals a 2D (4,4) network. Compound 10 shows a 3D 5-connected framework with (4(6).6(4)) topology. The effects of the L anions and the N-donor ligands on the structures of the coordination polymers have been discussed. In addition, the luminescent properties of 1, 3, 4 and 7-10 have also been investigated in details. (C) 2012 Elsevier Ltd. All rights reserved.
