Two 3D Supramolecular Coordination Polymers Constructed from Aromatic Carboxylic Acids and Flexible Bis(thiabendazole) Ligands

Two coordination polymers (CPs), [Zn(L1)(H2bta)] (1) and [Co(L2)(ndc)]·0.75H2O (2), (L1 = 1,6-(thiabendazole)hexane), L2 = 1,3-(thiabendazole)propane, H4bta = 1,2,4,5-benzenetetracarboxylic acid, H2ndc = 2,6-naphthalenedicarboxylic acid) have been hydrothermally synthesized and characterized. Single crystal X-ray diffraction analyses reveal that CP 1 and CP 2 feature 1D infinite zigzag and “Ω”-like chains, and further extend into 3D supramolecular framework by O–H⋯O and C–H⋯O hydrogen bonding interactions, respectively. Furthermore, the luminescence properties, thermal stability, and catalytic degradation of methyl orange in a Fenton-like process are also investigated in detail.
