- Department of Chemistry, Manipur University, Canchipur-795 003 Manuscript received 19 may 1995, revised 13 December 1995, accepted 15 December 1995 Mechanisms of the acid-mediated dissociation of two mixed chelate complexes, bis(acetylacetonato)ethylenediamine and acetylacetonatobis(ethylenediamine)cobalt(III) ions have been investigated spectrophotometrically. In the presence of perchloric acid the first complex dissociates to cobaltous ion, free ethylenediamine, free acetylacetone and oxidised products of acetylacetone. The dissociation follows an acid-assisted path. Rate constant (kobs) for the complexes have been evaluated. A mechanism has been proposed for the first complex.
