摘要：

Two new cadmium(II) complexes,[Cd2L2Cl4] (1) and [CdL2](ClO4)(2) (2) {L=8-[(pyridylmethyl)amino]-quinoline}, have been synthesized and characterized by X-ray single-crystal structure analysis. Each neutral L is a tridentate terminal ligand. Complex 2 is mononuclear compound whereas 1 is a di- chloride-bridged dinuclear compound. Interactions of the complexes with CT- DNA have been investigated by UV absorption, fluorescence and circular dichroism spectroscopy. Results show that the complexes bind to CT-DNA with moderate intercalation.
