Description	The kinetic inertness of copper(II) complexes with cyclen-based ligands having three (H(3)do3a) or four (H(4)dota) acetic acid arms and those with three acetic acid and one phosphonic (H(5)do3ap), phosphinic (H(5)do(3)ap(PrA) , H(4)do3ap(ABn)) acid or methylpyridine-N-oxide (H(3)do3a-pyNox) pendant arms has been studied. The proton-assisted decomplexation reaction was studied under a wide range of conditions to fully assess the parameters influencing the reaction (temperature range 25-60 degrees C, proton concentration range 0.05-5 M and presence of perchlorate or nitrate anions). The empirical rate law k(d,obs) = k(0) + k(H) x [H+], involving solvolytic and proton-assisted dissociation pathways, shows that the complexes can be divided into two groups according to their kinetic behavior.
