[Co(bamp)(camp)Cl][ZnCl_4]配合物的合成、分离与NMR结构解析

Synthesis,Separation and NMR Structure Analysis of the [Co(bamp)(camp)Cl][ZnCl_4] Complex

用过氧化物法合成,并通过Dowex50W×2(H+)阳离子交换柱分离得到[Co(bamp)(camp)Cl][ZnCl4](bamp=2,6-(二胺基次甲基)吡啶),camp=6-腈基-2-胺基次甲基吡啶)多吡啶环配合物.元素分析、质谱及13C,1HNMR检测表明:该目标配合物是一经式几何异构体(meridional geometrical isomer),分子结构具有σv对称性,且常常具有强配位能力的腈基(—CN)在此并不参与配位反应.

A new polypyridyl ligand complex of [Co（bamp）（camp）Cl][ZnCl4] was synthesized by decomposing peroxide complexes and was separated through Dowex 50 W ×2 （ H ^＋ ） column （ bamp = 2,6- （bisaminomethenyl） pyridine, camp = 6-cyano-2-（ aminomethenyl）pyridine）. The result showed that the cobalt （ Ⅲ） complex of one meridional geometrical isomer was of molecular structure with σv symmetry in which the eyanidyl group with always strong coordination capacity is now free in the title system by using element analysis, MS and ^1H NMR, ^13C NMR spectra.
