| 摘 要： | 采用水热方法,用含硫二羧酸配体4-((carboxymethyl)thio)benzoic acid(H2L)和4,4′-联吡啶(4,4′-bipy)分别与Co Cl2·6H2O和Mn Cl2·4H2O反应,合成了2个二维配位聚合物{Co(μ3-L)(4,4′-bipy)]·H2O}n(1)和{Mn(μ-L)(4,4′-bipy)(H2O)2]·H2O}n(2),并对其结构和光催化性质进行了研究。结构分析结果表明2个配合物分别属于三斜和单斜晶系、P1和P21/c空间群。配合物1和2分别具有基于双核Co和一维Mn链单元的二维层结构。配合物1和2具有不同的二维层结构是由于采用了不同的金属离子。另外,研究了2个配合物对有机染料亚甲基蓝的光催化降解性能,结果表明配合物2可以高效地降解亚甲基蓝。

| Abstract: | Two 2D cobalt(Ⅱ)and manganese(Ⅱ)coordination polymers,namely{Co(μ3-L)(4,4′-bipy)]·H2O}n(1)and{Mn(μ-L)(4,4′-bipy)(H2O)2]·H2O}n(2),have been constructed hydrothermally using 4-((carboxymethyl)thio)benzoic acid(H2L),4,4′-bipyridine(4,4′-bipy),and cobalt or manganese chlorides.Single-crystal X-ray diffraction analyses reveal that 1 and 2 crystallize in the triclinic and monoclinic systems,space groups P1 and P21/c,respectively.Complexes 1 and 2 show two different 2D sheets composed of dimer Co(Ⅱ)or 1D Mn(Ⅱ)chain units.The structural difference of 1 and 2 is driven by the metal(Ⅱ)nodes.The photocatalytic properties of two complex were investigated,showing that 2 is a promising photocatalyst for the UV-light-driven degradation of methylene blue as a model organic dye pollutant.CCDC:1967233,1;1967234,2. |
