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。
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.CCDC: 833603,2;833604,4.
