摘要
以4-(2’,4’-二羧基苯基)-2-吡啶甲酸为配体,Cu Cl2·2H2O为金属盐,采用溶剂热法合成了标题配合物。单晶结构解析表明,标题配合物属于三斜晶系,P-1空间群,单胞参数a=0. 776 1(8) nm,b=0. 787 3(9) nm,c=1. 202 0(13) nm,α=88. 56(4)°,β=82. 92(3)°,γ=67. 940(19)°。配体中只有一个羧基去质子化参与配位,因此标题配合物形成单核零维结构。进一步采用元素分析、红外光谱(IR)、X射线粉末衍射(PXRD)及热重分析(TGA)对标题配合物进行了结构表征,并研究了其对甲基橙(MO)的催化降解性能。结果表明,标题配合物在可见光下能够催化降解MO,降解率达79. 9%,是一种潜在的催化降解有机污染物的材料。
The title compound was constructed via solvothermal synthesis method with 4-(2',4'-dicarboxylphenyl)picolinic acid and copper chloride dihydrate.X-Ray single crystal diffraction revealed that the title compound crystalized in triclinic system,P-1 space group,unit cell parameters are a=0.7761(8)nm,b=0.7873(9)nm,c=1.2020(13)nm,α=88.56(4)°,β=82.92(3)°,andγ=67.940(19)°.Only one carboxyl group was deprotonated in the ligand and participates in the coordination,so the title compound formed a mononuclear zero-dimensional structure.The title compound was confirmed by elemental analysis,infrared spectroscopy,powder X-ray diffraction and thermogravimetric analysis.The catalytic degradation of methyl orange(MO)by the title compound was elucidated,and the resulted show that the title compound could degradate MO in visible light,and the degradation rate reached 79.9%,suggesting it was a potential material for catalytic degradation of organic pollutants.
