摘要: Three novel complexes containing ligand of N-phenyl norcantharidin acylamide acid (HL = 3-phenyl carbamoyl-7-oxabicyclo [2.2.1] heptane-2-carboxylic acid, C14H15NO4) were synthesized and characterized by elemental analyses, conductivity measurement, IR spectra, thermogravimetric analysis. The general formulas the [RE(L)(NO3)(H2O)2]NO3·2H2O, (RE ˭ Y(III), Gd(III), Dy(III)). results indicated that oxygen atoms carbonyl, cyclic ether, carboxylate coordinated to RE (III), there was also one nitrate taking part in coordination. RE(III) HL formed 1:1 chelate suggested coordination number eight. interactions between DNA have been investigated means fluorescence viscosity, agarose gel electrophoresis. showed could bind modes partly intercalation. binding abilities with follow trend: Dy(III) complex > Gd(III) Y(III) comple...
