N,N'-dimethylethylenediamine-N,N'-di-α-butyric acid(dmedba)와 세자리 아미노산과의 코발트(Ⅲ) 착물인 [Co(dmedba)(L-aa)] (L-aa = S-methyl-L-cysteine, L-methionine, L-glutamic acid, L-aspartic acid)는 s-cis-[Co(dmedba)Cl2]- 착물과 아미노산과의 반응으로부터 얻었다. 아미노산들은 [Co(dmedda)(L-dd)] 착물과 같이 아민과 카르복실그룹을 통하여 배위되었다. 이 착물들의 구조는 1H-NMR, IR, UV 스펙트럼 데이타와 원소분석으로 확인하였다.

Cobalt(Ⅲ) complexes of N,N'-dimethylethylenediamine-N,N'-di-α-butyric acid(dmedba) and trifunctional aminoacids, [Co(dmedba)(L-aa)] (L-aa = S-methyl-L-cysteine, L-methionine, L-glutamic acid, L-aspartic acid) have been prepared from the reaction between the s-cis-[Co(dmedba)Cl2]- complex and the amino acid. The amino acids have been found to coordinate through the amine and carboxylate groups just like [Co(dmedda)(L-aa)]. The complexes obtained in this work were characterized by their proton magnetic resonance, infrared and visible absorption spectral data along with the elemental analyses.
