✦ Synopsis

The binding mode of (en ‫ס‬ ‫ם3‬ Co(en) 3 ethylenediamine) to calf thymus DNA is investigated using electrochemical and spectroscopic methods. Binding constant value (K ‫ס‬ 1.284 ‫ן‬ 10 3 L/mol) is found to be the same by the two methods. Both isomers show the same CV behavior associated with binding to B-form DNA. CD spectra results show no enantoselectivety for both isomers binding to DNA. All of this evidence suggests that the com-

‫ם3‬

Co(en) 3 plex binds to DNA by an electrostatic mode.
