Thermodynamic studies on the complexation reaction of copper(II) macrocyclic tetramine complexes with hydroxide ion
Abstract
The relative stabilities of the red and blue forms of each of the complexes [CuL]2+ and [CuL(OH)]+(L =meso- or rac-5,5,7,12,12,14-hexamethyl-1,4,8,11-tetra-azacyclotetradecane) have been determined by a spectrophotometric method in basic solution at 25 °C and l= 0.1 mol dm–3. The factors which influence the relative stabilities are discussed.
