| 摘要: 在无水乙醇体系中设计合成了2种配合物:[Cu(L1)Cl2]·0.5C2H5OH(1)和Co(L1)Cl2(2)(L1=1,4-双(吡唑甲基)苯)。通过元素分析、红外光谱、热重、X-射线粉末和X-射线单晶衍射方法对其结构进行了表征,分析了其光谱及结构特征。结构分析表明,配合物1中金属配位数为5,形成四角锥构型,配合物2的中心金属配位数为4,形成了扭曲四面体构型,配体1,4-双(吡唑甲基)苯采取二齿桥联配位模式。通过仿生催化溴化动力学研究,发现上述配合物均表现出潜在的催化溴化活性。 | |

| Abstract: Two complexes [Cu(L1)Cl2]·0.5C2H5OH (1) and Co(L1)Cl2 (2) (L1=1,4-bis((1H-pyrazol-1-yl)methyl)benzene) were designed and synthesized in the anhydrous ethanol system. The spectrum and structural characters of the two complexes were analyzed by elemental analysis, IR spectrum, thermogravimetric analysis, powder X-ray diffraction and single crystal X-ray diffraction analysis. The structural analysis shows that the coordination numbers of metal in complexes 1 and 2 are five and four to form square pyramidal and distorted tetrahedron geometry, respectively, and ligand L1 is in bidentate coordination mode. In addition, complexes 1 and 2 had the mimic catalytic activity during brominating reaction process. | |
