Abstract：The interaction between Fe3(CO)12 and DNA was investigated by absorption and spectra, fluorescence spectra. The absorption of EB-DNA system in the presence of Fe3(CO)12 showed that Fe3(CO)12 could partly sustain the place of EB. The result of fluorescence spectra suggested that Fe3(CO)12 could enhance the fluorescence intensity of DNA sharply. All the experimental results indicated that the intercalative binding mode was the major model for the interaction of Fe3(CO)12 cluster complex with DNA.
