摘要：

Extended X-ray absorption fine structure (EXAFS) spectroscopy is applied to an investigation of the structural environment around Zn in polycrystalline K2ZnCi4 over the temperature range associated with its solid-to-solid phase transformations at 127 degrees C and 282 degrees C. The results show a reversible increase in thermal disorder and in the tetrahedral distortion of the ZnCl42- anion upon transformation into the incommensurate phase.
