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*ea T)(H2O)3]·2H2BTC·2H2O(1)和[Cu(Bpz*ea T)(H2O)3]·2H2BTC·CH3CH2OH·H2O(2)[Bpz*ea T=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.In the mixture of ethanol and water,two complexes [Co（ Bpz＊ ea T）（ H2O）3]·2H2BTC·2H2O（ 1） and [Cu（ Bpz＊ ea T）（ 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＊ ea T[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.
