The synthesis of a tripod Schiff-base ligand and its complexes with five rare earth nitrates are reported.All the compounds were characterized by elemental analysis,IR,TG-DTA,and molar-conductance measurement.The results showed that in the complexes the Ln:L ratio is 1:1,one nitrate group is free,the other two nitrate groups monodentately coordinate to the Ln(Ⅲ) ion,and the coordination number of the rare earth ion is 8.The interactions of the complexes with DNA were investigated by fluorescent spectroscopy,which showed that the complexes could be bound to DNA,and the binding mode of the complexes with DNA was intercalation.
