Abstract
Abstract Cobalt(II) complexes of diethylenetriamine-N,N′,N″-triacetic acid (DTTA) were prepared. From spectrophotometric and magnetic data, diaquo-DTTA-Co(II) was found to have an octahedral arrangement in which the N,N′-diacetate moiety and two water molecules are in the coordination sphere, and the terminal amino acid residue dangles outside. On heating the diaquo-complex, thermal rearrangement occurred with loss of water and the complex took a tetrahedral configuration. This was confirmed by its electronic spectrum and magnetic moment. The tetrahedral complex turned to another octahedral complex with absorption of water, the configuration of which seemed to differ from the original as judged by spectral difference. Cobalt(II) complexes of ethylenediamine-N,N′-diacetic acid (EDDA) were also prepared and investigated for the sake of comparison.
