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.

H2 biim ligands are located on both sides of the chain in chelating bidentate modes. Further, the H2 biim ligands from bridge chains by 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, the thermal behavior and the luminescent property of 1 have been investigated.
