摘要：A new 1D Cd（II） coordination polymer, [Cd（H2biim）2（SO4）]n·3n H2O（1, H2 biim = 2,2’-H2biimidazole）, has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction. It crystallizes in monoclinic, space group P21/c with a = 6.8405（14）, b = 17.792（4）, c = 14.987（3） A, β = 92.68（3）, V = 1822.1（6） A3, Z = 4, C12H18 Cd N8O7S, Mr = 530.80, Dc = 1.935 g/cm3, F（000） = 1064, μ（Mo Ka） = 1.371 mm-1, R = 0.0280 and w R = 0.0617. In 1, adjacent Cd（II） atoms are bridged by sulfate anions in bidentate modes to yield a 1D chain. H2 biim ligands are located on both sides of the chain in chelating bidentate modes. Further, the H2 biim ligands from neighboring chains are paired through π-π interactions to generate a supramolecular layer, which is stabilized by the complicated N–H···O and O–H···O hydrogen bonds. In addition, thermal behavior and luminescent property of 1 have been investigated.
