| 摘要: 通过改变溶剂热反应温度，合成了2个结构不同的镉配合物[Cd2（H2ppty）2（SO4）2（H2O）2]·3H2O（1）和[Cd2（ppty）（SO4）（H2O）2]n（2）（H2ppty=3，5-bis-（1H-pyrazol-3-yl）-[1，2，4]triazol-4-ylamine）。进一步的研究表明，1和2的结构分别包含有双核和四核镉簇单元，呈现出零维和二维的结构。并且在室温下对2个配合物的荧光性质也进行了测试。固体紫外漫反射表明1和2的光学带隙分别为1.87和2.32 eV，因此它们对亚甲基蓝的光降解反应表现出了良好的催化活性。 | |

| Abstract: By changing solvothermal temperature, two new Cd(Ⅱ))-based coordination complexes[Cd2(H2ppty)2(SO4)2(H2O)2]·3H2O (1) and[Cd2(ppty)(SO4)(H2O)2]n (2), (H2ppty=3,5-bis-(1H-pyrazol-3-yl)-[1,2,4] triazol-4-ylamine) have been synthesized and structurally characterized. Further investigation indicates that the final structures of 1 and 2 containing binuclear and tetranuclear clusters show zero-(0D) and two-dimensional (2D) structures, respectively. Moreover, luminescent properties of the two complexes are examined in the solid state at room temperature. The UV-Vis diffuse reflectance measurements reveal that the two compounds possess semiconductor behaviors with smaller band gaps of 1.87 and 2.32 eV, and show effective photocatalytic degradation activities over organic pollutant under visible-light irradiation. | |
