The stabilization of monovalent copper ions by complexation with saturated tertiary amine ligands in aqueous solutions. The case of 2,5,9,12-tetramethyl-2,5,9,12-tetraazatridecane

Abstract

The complex of copper(I) ions with 2,5,9,12-tetramethyl-2,5,9,12-tetraazatridecane in aqueous solutions is stable in the absence of oxygen; this observation indicates that the stabilization of low valent transition metal cations by tertiary tetraazamacrocylic ligands is due to the hydrophobic nature of these ligands.
