“…Among the various mechanisms through which they carry on their action in bioenvironments, of utmost importance is their direct interaction with DNA. Many DNA binding studies of metal complexes of Salen-type ligands have been reported in the literature, for example of Al [1], V [2], Mn [3][4][5][6][7], Fe [8,9], Co [6,10] Ni [2,5,6,11] Cu [2,6,12,13] and Zn [2]. The capability to interact with DNA is determined by several factors such as the nature of the ligand and the coordination geometry.…”
