[Co(ptma)(amp)Cl][ZnCl_4]体系配合物异构体的合成及分离

Synthesis and Separation of Isomers in[Co(ptma)(amp)Cl][ZnCl_4]

用过氧化物法合成了 [Co( ptma) ( amp) Cl][Zn Cl4]体系的异构体混合物 ( ptma=N-( 2 -吡啶基甲基 )丙二胺 ,amp=2 -(氨基甲基 )吡啶 ) ,并通过 Dowex( H+ )阳离子交换柱分离得到 4带配合物 ,将配合物用H2 Zn Cl4结晶 .1 3 C及1 H NMR检测表明 ,其中第二带、第四带是标题体系中的异构体且配合物阳离子中可能具有 C— H…π结构 .

Two isomers in[Co(ptma)(amp)Cl] system have been synthesized by decomposing per-oxide complexes (ptma=N-(2-pyridylmethyl)propylenediamine;amp = 2-(Aminomethyl)pyridine). Four bands were developed on a Dowex(H+) column, the tetrachloride zincate salt of the complexes of the second and fourth bands have been suggested to be the isomers with C-H...πstructure in title system by using 13C and 1H NMR spectra.
