Abstract:

Four coordination compounds of transition metal with 3,5-diiodo-salicylalidehyde and salicyhydrazide Schiff base have been synthesized in pyridine and DMF solvents. These ligand and complexes were characterized by UV and IR spectra, TG-DTG, elemental analysis, and molar conductance analysis. The interactions of the complexes with DNA were investigated by UV and fluorescence spectroscopies, which show that the binding mode of the complexes with ct-DNA was intercalation. In addition, the biological activity test reveals that the complexes have potentially catalytic and antibacterial activity towards superoxide anion radical O-·2 and Micrococcus luteus.

Key words: iodine-containing Schiff base, transition metal complexes, spectrum character, antibacterial activity
