Abstract New two copper complexes of type [Cu(Bzimpy)(L)H 2 O]SO 4 (where L = 2,2′ bipyridine (bpy), and ethylene diamine (en)), Bzimpy = 2,6-bis(benzimidazole-2yl)pyridine have been synthesized and characterized by elemental analyses, molar conductance measurements, magnetic susceptibility measurements, mass, IR, electronic and EPR spectral studies. Based on elemental and spectral studies six coordinated geometries were assigned to the two complexes. DNA-binding properties of these metal complexes were investigated using absorption spectroscopy, fluorescence spectroscopy, viscosity measurements and thermal denaturation methods. Experimental studies suggest that the complexes bind to DNA through intercalation. These complexes also promote the cleavage of plasmid pBR322, in the presence of H 2 O 2 .
