A novel coordination polymer {[Co-2(tdpa)(bpe)(1.5)(H2O)]center dot(bpe)(0.5)center dot(H2O)} (n) (1) has been hydrothermally synthesized through the reaction of 2,3,2',3'-thiodiphthalic acid (H(4)tdpa) with divalent cobalt salt in the presence of ancillary nitrogen ligand (bpe = trans-1,2-bis(4-pyridyl)ethene) and characterized by IR spectra, elemental analysis and single crystal X-ray diffraction. Due to various coordination modes and conformations of the versatile 2,3,2',3'-thiodiphthalic acid ligand, the complex exhibits structural and dimensional novelty. In complex 1, metal-organic ribbons (Co-tdpa) are connected together through bpe ligands to generate a three-dimensional (3D) metal-organic framework. The structure of 1 can be described as a (3,6)-connected network with a Schlafli symbol of (4(2)center dot 6)(4(4)center dot 6(10)center dot 8) topology. The thermal stability of the complex 1 was studied by thermal gravimetric analyses (TGA), and the UV-vis absorption property of complex 1 was also investigated.
