Abstract
Abstract A novel copper (II) complex, [Cu(HL)2] (where, HL = 3-(4-(sulphonamine)phenylimino)-1-phenylbut-1-en-1-ol) has been synthesized and characterized by IR, UV–vis, magnetic susceptibility measurement and single crystal X-ray crystallographic studies. The crystal data confirm the square planarity of the prepared complex having an orthorhombic space group Pca2 (1). Molecular packing of the complex is stabilized by N―H…O hydrogen bonding and weak N―H…O, C―H…Cg π-ring intermolecular interactions, hence forming a two dimensional supramolecular network structure. CT-DNA binding studies have been carried out by monitoring electronic absorption titrations, luminescence titrations, a DNA melting, cyclic voltametry and viscosity measurement studies. An intercalative mode of DNA binding is suggested for the prepared copper (II) complex.
