【Abstract】 The synthesis and characterization for the complexes of rare earth with 3-(4-hydroxy-3-methoxy benzo) propenoic acid in aqueous solution have been reported. According to chemical analysis, the composition of new complexes are RE(C10H9O4)3.xH2O, where RE stands for La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Y, x equals 2 or 1. The structure and property of these complexes were studied by chemical analysis, infrared, proton magnetic resonance spectrum and thermo-gravimetric analysis.更多还原
