Four Cd(II) coordination polymers (CPs) including [Cd(btbb)_0.5(L1)]_n (1), [Cd(btbb)(L2)·(H₂O)_1.5]_n (2), [Cd(btbb)(L3)]_n (3), and [Cd(btbb)(HL4)]_n (4) (btbb = 1,4-bis(thiabendazole)butane, H₂L1 = 5-hydroxyisophthalic acid, H₂L2 = 4,4′-biphenyldicarboxylic acid, H₂L3 = tetrabromoterephthalic acid, H₃L4 = 5-nitro-1,2,3-benzenetricarboxylic acid) were prepared under hydrothermal conditions based on flexible bis(thiabendazole) ligand and different co-carboxylates. Their structures have been determined by single-crystal X-ray diffraction analyses, elemental analyses, IR spectra, X-ray powder diffraction, and thermogravimetric analyses. CP 1 exhibits a 3D 2-nodal (3,4)-connected framework with the 3,4T10 topology. CP 2 and 3 feature typical hcb layer structure, and 3 is further combined into a 3D supramolecular architecture through C–H⋯O hydrogen bonds. CP 4 possesses an infinite chain and further extended into 2D supramolecular network by O–H⋯O hydrogen-bonding interactions. The effects of the aromatic polycarboxylate co-ligands on the CPs framework have been discussed and the catalytic activities of CPs 1–4 for degradation of methyl orange in Fenton-like process are also investigated.
