Unveiling the Fluorination Pathway of Ruddlesden-Popper Oxyfluorides: A Comprehensive <i>In Situ</i> X-ray and Neutron Diffraction Study.

ABSTRACT: Ruddlesden-Popper oxyfluorides exhibit unique properties, but their synthesis is often hindered by low thermodynamic stability. To overcome this challenge, understanding the formation mechanism of these materials is crucial for optimizing the reaction conditions and accessing new products. This study presents an in-depth investigation of the fluorination reaction of La₂NiO₄ with poly(vinylidene fluoride) (PVDF), targeting the oxyfluorides La₂NiO₃F₂ and La₂NiO_2.5F₃, which exhibit distinct structural distortions. In situ X-ray diffraction experiments, performed on a laboratory diffractometer, revealed the presence of four distinct reaction intermediates. The crystal structures of these intermediate
