Influence of carboxamido nitrogen donors on the redox potential of copper(III) complexes

The synthesis of a new copper(III) complex with aliphatic carboxamido-N and thiolato-S donors is reported. This complex was thoroughly characterized by ¹H NMR, UV–Vis spectroscopy, and cyclic voltammetry, as well as by single crystal X-ray crystallography. The copper(III) state in this complex is more stabilized than in the parent compound with aromatic carboxamido nitrogen donors.
