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.
