Kopsavilkums

The local atomic structure in α- and β-SnWO₄ was studied by synchrotron radiation W L₃-edge x-ray absorption spectroscopy at 10 and 300 K. Strongly distorted WO₆ octahedra were found in α-SnWO₄, whereas nearly regular WO₄ tetrahedra were observed in β-SnWO₄, confirming previous results. The structural results obtained were supported by the first-principles calculations, suggesting that the second-order Jahn-Teller effect is responsible for octahedral distortion.
