Structural phase transitions of ionic layered PbFX (X=Cl−or Br–) compounds under high pressure

[Display omitted] The PbFX (X=Cl–or Br–) compounds crystallize in tetragonal structure with space group P4/nmm. High pressure X-ray diffraction studies carried out on PbFCl compound reveals that it undergoes pressure induced structural transitions at ∼18GPa and ∼38GPa to orthorhombic and monoclinic...
