THE ISOLATION AND CHARACTERIZATION OF COBALT(III) COMPLEXES OBTAINED FROM THE REACTIONS OF ETHYLENEDIAMINETETRAACETATO-AND R-PROPYLENEDIAMINETETRAACETATO-COBALTATE(III) WITH ETHYLENEDIAMINE

Abstract Five new mixed ligand cobalt(III) complexes containing ethylenediamine(or R-propylenediamine)tetra(or tri)acetate and ethylenediamine have been obtained by the reactions of [Co(edta)]− and [Co(R-pdta)]− with ethylenediamine in water. The reactivity of these mixed complexes with ethylenediamine contradicts the mechanism of the reactions of [Co(edta)]− and [Co(pdta)]− with ethylenediamine proposed by Busch et.al.
