Abstract

The equilibrium constants for mixed binuclear complex formation between certain bivalent transition metal-EDTA complexes and various cyano-complexes in aqueous solution have been obtained from spectrophotometric measurements. The results can be interpreted to obtain the order of strength of binuclear complex formation with metal (II) which is: Cu>> Ni > Co; with aminocarboxylate complexes; NTA > EDDA HEDTA >EDTA>PDTA >CDTA: anfl with cyano complexes; Fe(CN)4- 6 ~ u(CN)4- 6>> Fe(CN)3- 6>Fe(CN)5 (NO)2-
