中文摘要：配体吡嗪-2-甲酸将其与CaCl_(2)和CuSO_(4)·5H_(2)O在水溶液中反应得到了两个新的单核钙和铜配合物。并通过X-射线单晶衍射、红外和元素分析表征了其晶体结构。配合物1为一个Ca(Ⅱ)离子与二个配体和四个配位水分子形成的单核结构,配合物2为一个Cu(Ⅱ)离子与一个配体和一个配位水分子形成的单核结构,单核结构之间通过O—H…H、N—H…H氢键作用组装成三维超分子网络结构。测试了配合物的紫外可见光和荧光吸收及配合物2非均相类Fenton试剂的催化性质。测试结果表明,两个配合物在不同溶剂中紫外可见吸收峰均在268 nm,配合物1固态荧光发射峰在414 nm和441 nm及配合物1和2在不同溶剂中荧光发射峰均为364 nm。含Cu(Ⅱ)的配合物2对甲基橙(MO)溶液可以达到81.76%的降解率,显示了良好的类Fenton催化性质,表明其是一种潜在的催化降解有机污染物材料。

外文摘要：A ligand pyrazinecarboxylic acid,which was further reacted with CaCl_(2)and CuSO_(4)·5H_(2)O under aqueous solution for final a two new mononuclear complex.The structure of obtained two mononuclear complex was characterized by X-ray crystal diffraction,IR and elemental analysis.The results showed that the complexs 1 is a mononuclear unit with Ca(Ⅱ)center coordinated with two ligand and four water molecules and the complexs 2 is a mononuclear unit with Cu(Ⅱ)center coordinated with one ligand and one water molecules,3D supermolecular was formed by O—H…H and N—H…H hydrogen bonds interactions.In addition,the UVVis and fluorescence spectroscopy of the complex and catalytic property of the complex for the methyl orange(MO)degradation as Fenton-like reagent were investigated.The results show that the UV-visible absorption peaks of the two complexes in different solvents are at 268 nm,the solid-state fluorescence emission peaks of complex 1 are at 414 nm and 441 nm,and the liquid-state fluorescence emission peaks of complexes 1 and 2 in different solvents are at 364 nm.The Cu(Ⅱ)mononuclear complex exhibited Fenton-like catalytic property with the degradation rate of MO reaching 81.76%,suggesting a potential material for catalytic degradation of organic pollutants.
