摘 要: | Two zinc(Ⅱ) complexes, namely, Zn(L_1)Cl_2]_2(1) and {Zn(L_2)(tbta)]·3H_2O}n(2)(L_1 = 1,3-bis(2-methylbenzimidazol-1-ylmethyl)benzene, H2 tbta = tetrabromoterephthalic acid, L2_ = 1,3-bis(2-methylbenzimidazol-1-yl)-2-propanol), have been successfully obtained under hydrothermal conditions. Complex 1 displays a binuclear structure which is further extended into a 1D supramolecular chain through π-π stacking. Complex 2 features a 2D(4,4) network based on a L2/tbta2- double linker. The thermal stability, fluorescence properties and catalytic activities of two complexes for the degradation of methyl orange in a Fenton-like process were discussed.
