A CONVENIENT METHOD FOR THE PREPARATION OF AMINOETHYLIMINODIACETATOCOBALT(III) COMPLEXES

Sodium dinitro(aminoethyliminodiacetato)-cobaltate(III) has been obtained by the oxidation of an aqueous mixture of cobalt(II) chloride, sodium nitrite, and a reaction product between ethylenediamine and sodium monochloroacetate. Several other complexes with the tetradentate ligand have also been derived from the dinitro complex.
