dc.descriptionThe high-pressure behaviour of alpha-PbF2 has been investigated by angular-dispersive synchrotron X-ray powder diffraction up to 6.55(8) GPa. The fit of a 3rd-order Birch-Murnaghan equation-of-state gave the volume at zero pressure V0=194.14(4)Å$^3 and the bulk modulus b_0=47.0(6)GPa with the pressure derivative b'=7.9(4). The continuous-symmetry-measure approach has been used for the quantification of the distortion of the coordination polyhedron in alpha-PbF2 revealing an increasing distortion with pressure. keywords here: high pressure, X-ray diffraction, inorganic compounds PACS: 61.10.N2, 62.50.+P, 64.20.+t, 07.35, 61.10.-i
