摘要: 利用过氧化物合成分解法制备得到一新的[Co(N-(2-Aminoethyl)-1,3propanediamine)(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。 |

Abstract: Some geometric isomers in a new [Co(N-(2-Aminoethyl)-1,3-propanediamine)(1,2-diamino -2-methylpropane)Cl]2+ system were synthesised by decomposing a per-oxide complex of [(Co(2,3-tri)(ibn))2O2](ClO4)4.The crystal structure of one of the anti-form isomers (referring to Cl) was resolved by using single crystal X-ray determination, it belongs to orthorhombic with space group P212121(#19),a=1.3599(3)nm,b=1.6146(3)nm,c=0.9288(2)nm,V=2.0394(8)nm3,Dc=1.710g·cm-3,Z=4,F000=1072.00, μ(MoKα)=26.50cm-1,R=0.043,Rw=0.051. There are four complex cations which are enantiomer in a unit cell. The structure of one of the syn-form isomers in DMSO was resolved by using 2D NMR techniques(gCOSY and NOESY spectra). |
