利用过氧化物合成分解法制备得到一新的 [Co(N-(2-Aminoethyl)-1,3 propanediamine)(1,2-diamino-2-methylpropane)Cl]~(2＋)体系配合物，并用柱层析分离得到部分几何异构体。用单晶 X-射线衍射分析方法解析了其中一反式（三元胺仲氮上的氢相对于 Cl）经式异构体的晶体结构，用二维核磁共振技术的同核质子相关 gCOSY及 NOESY谱解析了其中一顺式（三元胺仲氮上的氢相对于 Cl）经式异构体在溶液中的结构。
A novel [Co (N- (2-Aminoethyl) -1,3 propanediamine (1,2-diamino-2-methylpropane) Cl] 2+ complex was prepared by peroxide synthesis and decomposition method. Column chromatographic separation of some of the geometric isomers. The crystal structure of one of the trans (the hydrogen on the secondary amine of the tertiary amine to Cl) is resolved by single crystal X-ray diffraction analysis. The two-dimensional nuclear magnetic resonance technique of the homonuclear proton-related gCOSY and The NOESY spectrum analyzes the structure of one of the cis (the hydrogen on the tertiary amine to Cl) meso-isomer in solution.
