摘要 用过氧化物法合成 ,并通过Dowex(H+)阳离子交换柱分离得到 [Co( 2 ,6 bamp) (aep)Cl][ZnCl4](bamp =2 ,6 (二氨基甲基 )吡啶 ,aep =2 (氨基乙基 )吡啶 )体系的一异构体 ,将配合物用H2 ZnCl4结晶。其NMR谱的检测表明 ,初步论证了该配合物是所要合成的一异构体 ,通过量化计算的结果 ,此异构体阳离子中可能具有C—H… An isomer of [Co(2,6 (bisAminomethyl)pyridine)(2 (Aminoethyl)pyridine)Cl] system has been synthesized by decomposing per oxide complexes. NMR analysis show that the complexes of the second band is one of the two isomer m1 properly with C—H…πstructure by a computational result of RHF/LANL2DZ optimized total energy for the title system.
