Abstract

Cobalt(III) complexes of N,N'-dimethylethylenediamine-N,N'-di-${\alpha}$-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)Cl_2]-^$ 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.
