Abstrakt: In order to study the local structure of some antimony compounds, Sb K‐edge XAFS spectra were measured for Sb2Te3and InSb. The measurements were performed in the transmission mode at BL‐01 of SPring‐8. Though crystal structure of antimony telluride Sb2Te3is known by X‐ray diffraction analysis, the EXAFS analyses give controversial result on the Sb‐Te distance and the coordination number of Sb2Te3. Comparing the observed XANES spectra for Sb2Te3with FEFF8 calculation, we can explain the controversial results which are also supported by the observed X‐ray powder diffraction.
