摘　　要：采用水热法,以MnSO_(4)·H_(2)O和4-(3,5-二羧基苯基)-吡啶甲酸(H_(3)pja)为原料合成了一例新的Mn配合物,其分子式为[Mn_(3)(H_(2)pja)_(2)(Hpja)_(2)(H_(2)O)_(8)]·2H_(2)O(简称配合物Mn).采用X-射线单晶衍射对其进行了结构解析,结果表明该配合物为零维结构.采用X射线粉末衍射表征了其相纯度.并且重点研究了配合物Mn在可见光照射下对有机染料分子甲基橙(MO)、罗丹明B(RhB)的光催化降解性能.结果表明,配合物Mn对甲基橙有一定的催化降解效果,降解率为61.9%,而对罗丹明B的催化降解效果更好,降解率可达98.5%.A new Mn complex was synthesized from MnSO_(4)·H_(2)O and 4-(3,5-dicarboxyphenyl)-picolinic acid(H_(3)pja)as raw materials by hydrothermal method.Its molecular formula is[Mn 3(H_(2)pja)_(2)(Hpja)_(2)(H_(2)O)_(8)]·2H_(2)O(Complex Mn).The structure of the complex was analyzed by single crystal X-ray diffraction.The results show that the complex is zero-dimensional structure.The phase purity was characterized by X-ray powder diffraction.The photocatalytic degradation properties of Complex Mn on organic dye molecules methyl orange(MO)and Rhodamine B(RhB)under visible light irradiation were studied.The results showed that Complex Mn had a certain catalytic degradation effect on MO with a degradation rate of 61.9%,while RhB had a better catalytic degradation effect with a degradation rate of 98.5%.
