SYNTHESIS AND CRYSTAL STRUCTURE OF s-cis-(ETHYLENEDIAMINE-N,N′-DIACETATO)COBALT(III) COMPLEX WITH N,N-DIMETHYLGLYCINE

ABSTRACT

The s-cis-geometrical isomer of the cobalt(III) complex with N,N-dimethylglycine (dmgly) and the tetradentate ligand ethylenediamine-N,N′-diacetate ion (edda) was prepared by a direct synthesis from cobalt(II) chloride hexahydrate, N,N-dimethylglycine and edda in the presence of lead(IV) oxide. The complex has been isolated chromatographically and characterized by elemental analyses, electron absorption spectra, infrared spectra and X-ray diffraction analysis.
