Description	Thermodynamic and kinetic properties of Cu(II) complexes with macrocyclic cyclen ligands having four phosphonic acid monoester (H4dotpOEt) or four phosphinic acid (H4dotpH) and H4dotpPh) pendant arms were investigated. The formation kinetics carried out in pH range 1-5.5 (t = 25 C, I = 0.1 M KCl) shows that reactive species are (H2L)2- and (HL)3- anions and their reactivity differs by 4-5 orders of magnitude. Among studied ligands, H4dotpH is the most reactive one. Dissociation of these copper(II) complexes was investigated in the presence of perchloric acid (I = 5 M (Na,H)ClO4, proton concentration range 0.1–5.0 M) and in temperature range 10-35 C. All studied complexes are less kinetically inert than the [Cu(dota)]2- complex and the Cu(II) complex of H4dotpH is the least kinetically inert among the studied complexes, probably due to the lowest thermodynamic stability.
