In order to get the information of interaction between metal complex and DNA and select metal complexes which can cleave DNA effectively, twenty seven transition metal complexes containing O/N coordinate atoms have been synthesized in this thesis. We report the synthesis, crystal structure and properties of the complexes. One of the complexes is the first μ〓-oxalato tetranuclear Cu complex, in which there is ferromagnetic interaction between the copper atoms bridged by oxalate ions. Two trinuclear copper complexes containing partial cubane Cu〓O〓 cores have been synthesized and discussed the magnetic properties.

But the electrochemical results show that complexes exhibitcompletely irreversible redox behaviour which is different from thatfound in diiron proteins. 1.3 To obtain the diiron species which are stable to elec-trochemical reduction, a series of new tetranuclear cage ironspecies containing two 〓 cores, with using hexadentatepolybenzimidazole ligands, were synthesized and characterized by vari-ous spectroscopic methods. Their physical properties have been investi-gated. The crystal structures of 〓〓tetrakis (benzimidazol-2-ylmethyl)-1, 4-diaminobutane and 〓,〓-tetrakis ( N-ethylbenzimidazol-2-ylmethyl )-1, 4-diaminobutane were determined. They contain two 〓 cores which arelinked to each other by -〓-chain in the ligands.
