| 摘 要： | 在有机溶剂中,我们设计合成了4种配合物:[Cu2Cl4pz*2](1),[Cu2Cl4(L2)2](2),[CuCl(L2)2H2O]Cl.H2O(3),[Ag(L3)2]NO3(4)(pz*=3,5-二甲基吡唑;L2=二吡唑甲烷;L3=4-碘-3,5-二甲基吡唑)。通过元素分析、红外光谱、紫外光谱、X-ray粉末和X-ray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,吡唑烷均采取二齿配位模式,配合物1、3和4中金属的配位数分别为五、六和二;配合物2中则存在2种不同配位模式的中心铜离子。并用Gaussian03量子化学程序包,采用密度泛函理论(DFT)中的B3LYP方法,研究了3个铜配合物的稳定性和电荷分布。 |

| Abstract: | Four complexes [Cu2Cl4pz*2] (1), [Cu2Cl4(L2)2] (2), [CuCl(L2)2·H2O]Cl·H2O (3) and [Ag(L3)2]NO3 (4) (pz*=3,5-dimethyl-1H-pyrazole, L2=di(1H-pyrazol-1-yl)methane, L3=4-iodo-3,5-dimethyl-1H-pyrazole) were designed and synthesized in the organic solvent system. The spectrum and structural characters of the four complexes were analyzed by elemental analysis, IR spectrum, UV spectrum, X-ray powder and X-ray monocrystal diffraction technology. The structural analysis shows that all pyrazolidines are in bidentate coordination mode and the coordination numbers of metal in complexes 1, 3 and 4 are five, six and two, respectively. However, there are two coordination modes for copper in complex 2. Furthermore, The stabilities and charge distribution of the three copper complexes were calculated by quantum chemistry.
