摘要:

在水和乙醇的混合体系中合成了2个配位化合物[Co(Bpz*eaT)(H2O)3]·2H2BTC·2H2O(1)和[Cu(Bpz*eaT)(H2O)3]·2H2BTC·CH3CH2OH·H2O(2)[Bpz*eaT=2,4-二(3,5-二甲基吡唑)-6-二乙胺基-1,3,5-三嗪; H3BTC=均苯三甲酸]. 通过元素分析、 红外光谱、 紫外光谱、 热重分析、 X射线粉末衍射以及X射线单晶衍射方法对配合物进行了表征. 结构分析表明, 配合物1和2的中心金属均为六配位, 形成扭曲的八面体构型. 通过分子间氢键的作用, 配合物1和2分别被连接成三维和二维的超分子结构. 此外, 对2个配合物的光催化活性进行了研究.

Abstract:

In the mixture of ethanol and water, two complexes [Co(Bpz*eaT)(H2O)3]·2H2BTC·2H2O(1) and [Cu(Bpz*eaT)(H2O)3]·2H2BTC·CH3CH2OH·H2O(2) were designed and synthesized via the reaction of metal salts and ligands H3BTC(benzene-1,3,5-tricarboxylic acid) and Bpz*eaT[2,4-bis(3,5-dimethylpyrazol-1-yl)-6-diethylamino-1,3,5-triazine]. The complexes were characterized by elemental analysis, IR spectrometry, UV-Vis spectrometry, thermal gravimetric analysis, X-ray powder and X-ray single crystal diffraction analysis. Structural analysis reveals that both complexes 1 and 2 form distorted octahedral geometry, and complex 1 has a 3D network structure and complex 2 has a 2D layer structure via hydrogen bonding connection. Furthermore, the photocatalytic performances of complexes 1 and 2 were studied and the result revealed that the photocatalytic activity of complex 1 was better than that of complex 2.
