EXAFS ANALYSIS WITHOUT MODEL COMPOUND FOR THE FIRST TRANSITION METAL COMPLEXES

Abstract

EXAFS for a series of simple six- and four-coordinate first transition metal complexes are studied. It is found that the peak intensities in the EXAFS Fourier transforms for aqua complexes correlate with those for ammine complexes and that the same is true for chloro complexes with bromo complexes. Quantitative analyses of EXAFS parameters by using curve-fitting calculations are performed. It is found that it is possible to estimate the parameter values for a certain combination of metal ion and ligand without the model compounds.
