Synthesis, characterization, DNA binding properties and antioxidant activity of a manganese(II) complex with NO6 chromophore.

The mononuclear complex [Mn(thiophenyl-2-carboxylate)(2)(H(3)tea)] (1), where H(3)tea=triethanolamine has been synthesized, characterized, while the DNA binding properties and the antioxidant activity were studied. The crystal structure of 1 is also reported. The interaction between 1 and calf thymus double stranded (ds) DNA was electrochemically at a calf thymus DNA (CT-DNA) modified carbon paste electrode (CPE) and spectrophotometrically investigated, respectively.
