Protonation and the overall complexation constants of copper(II) complexes of two dioxotetraza mono- and two bis-macrocycles were determined by potentiometry. Complexation sequence was elucidated for each ligand by means of UV/Vis and EPR spectroscopy. According to the ligand structure, two complexation mechanisms can be characterized.
