In order to study the local structure of some antimony compounds, Sb K‐edge XAFS spectra were measured for Sb 2 Te 3 and InSb. The measurements were performed in the transmission mode at BL‐01 of SPring‐8. Though crystal structure of antimony telluride Sb 2 Te 3 is known by X‐ray diffraction analysis, the EXAFS analyses give controversial result on the Sb‐Te distance and the coordination number of Sb 2 Te 3 . Comparing the observed XANES spectra for Sb 2 Te 3 with FEFF8 calculation, we can explain the controversial results which are also supported by the observed X‐ray powder diffraction.
