Electrochemical behaviour of acyclic and macrocyclic complexes of nickel(II), copper(II) and uranyl(VI)

Abstract

The electrochemical behaviour of a series of mono-nuclear, homo- and hetero-dinuclear complexes of dioxouranium(VI), nickel(II) and copper(II) ions with acyclic and cyclic compartmental ligands, derived from the condensation of 2,6-diformyl-4-chlorophenol and polyamines of the type NH 2(CH 2) 2X(CH 2) 2NH 2 (XNH, S), is reported. The kinetic and thermodynamic aspects governing the electrode mechanism are also discussed with respect to the different ligand designs and their differences in the donor atom sets.
