Interaction between the metals in cobalt(II)–copper(II), cobalt(II)–chromium(III) and iron(II)–chromium(III) cation pairs in the presence of α-amino acids and acetate anion in aqueous solutions

Abstract

Changes in visible absorption have been found for cobalt(II)–copper (II), cobalt(II)–chromium(III) and iron(II)–chromium(III) Cations pairs compared with separate metals in the presence of α-amino acid and acetate anion in aqueous solutions; it is concluded that bimetal cations stabilized by the ligands are formed.
