| PREPARATION AND SPECTROSCOPIC CHARACTERIZATION OF TRIMETHYLAMINE OXIDE COMPLEXES OF RARE EARTH ELEMENTS |

| 摘要: 尽管文献报道了三甲胺氧化物与Mn、Co、Ni、Zn、Cd、Cu等多种离子在有机溶剂中形成较稳定的配合物。但对其金属配合物的研究远不如芳香族杂环化合物那样引起人们广泛的注意。本文研究了它与希土元素形成配合物的合成和光谱性质。 |

| Abstract: Even coordination compounds of rare earth Elements (Ⅲ) with trimethylamine oxide have been prepared in anhydrous alcohol.In contrast to aromatic amine oxide ,N-O stretching frequencies for trimetbylamine oxide show little shift to lower frequency region after coordination to metal ions.This is attributed to the fact that no conjugated double bond exists in the molecule.The splitting of the Raman band at 943 cm-1 and the intensifi cation in the vicinity of 932 cm-1 indicate ,that ooth coordinated and free perchlorate groups exist in RELx(ClO4)3(x=6,or 5) in complexes ,REL3(NO3)3,the presence of free and coordinated nitrate groups is confirmed by the characteristic absorptions at 1046-1055 and 991-998cm-1 and the appearance of two new bands at 722cm-1 171cm-1 respectively. |
