| 摘 要： | 本文用EXAFS谱研究了三个固体铒甘氨基酸配位化合物, 得到铒甘氨酸和铒组氨酸的第一配位层Er-O键长分别为2.35和2.32A, 配位数分别为8.3和8.0. 并进一步用EXAFS径向结构函数图, 讨论了与其结构类型的关系, 推测出铒氨基酸配位化合物晶体的所属可能结构类型。

| Abstract: | Three solid erbium-amino acid complexes were studied by EXAFS. Among the 3 solid complexes, the erbium-serine complex Er2.(Ser)3.(ClO4)6.(dioxane)4.10H2O, which has been determine by x-ray crystallog., was used as the standard sample to extract the structural coefficients The relationship between the structural types of the complexes and the radial-structure-function (RSF) from EXAFS are discussed. Comparing the second peaks of the RSF, possible structures for the erbium-amino acid complexes were proposed. |
