Glycinato, L-alaninato, ethylenediamine, N,N-dimethylethylenediamine, (R)-propylenediamine, (R,R)-1,2-cyclohexanediamine and meso-2,3-butanediamine cobalt(III) complexes of a tripodlike ligand, N-(2-aminoethyl)iminodiacetate have been prepared. The geometrical configurations are assigned on the basis of their absorption, circular dichroism, and 1H-NMR spectra. The trans(O) isomer of meso-2,3-butanediamine
Glycinato、L-丙二胺、乙二胺、N,N-二甲基乙二胺、(R)-丙二胺、(R,R)-1,2-环己二胺和内消旋-2,3-丁二胺钴(III)配合物的三脚架配体,N -(2-氨基乙基)亚氨基二乙酸酯已制备。几何构型是根据它们的吸收、圆二色性和 1H-NMR 光谱确定的。内消旋-2,3-丁二胺配合物的反式(O)异构体被光学拆分,并讨论了手性1,2-二胺配合物的绝对构型与其圆二色性之间的关系。
