摘要: Two zinc(Ⅱ) complexes, namely,[Zn(L₁)Cl₂]₂ (1) and {[Zn(L₂)(tbta)]·3H₂O}ⁿ (2) (L₁=1,3-bis(2-methylbenzimidazol-1-ylmethyl)benzene, H₂tbta=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/tbta^2- 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.
