7.3 all the copper(II) complexes are mononuclear, mainly under their phenolate neutral form (except 3+), with a coordinated solvent molecule. The DNA cleavage activity of the complexes was tested towards the ϕX174 DNA plasmid. In the absence of an exogenous agent 12+ does not show any cleavage activity, 2+ and 3+ are moderately active, while 4+, 5+ and 6+ exhibit a high nuclease activity. Experiments
