Low temperature structural modification in Rb2ZrF6: Investigations by perturbed angular correlation spectroscopy
文摘

Crystalline compounds Rb2ZrF6 and Cs2HfF6 have been studied by TDPAC.

We have found four different structural modifications of Rb2ZrF6.

Two new structures have been found at room temperature.

Different structural modifications in Rb2ZrF6 probably arise due to rotation of the octahedral ionic group ZrF62−.

For the analogues compound Cs2HfF6, only two structural modifications have been found.
