Abstract

The high-pressure behaviour of α-PbF₂ was investigated by angular-dispersive synchrotron X-ray powder diffraction up to 6.55(8)GPa. The fit of a third-order Birch-Murnaghan equation-of-state gave the volume at zero pressure V₀ = 194.14(4)Å³ and the bulk modulus b₀ = 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 α-PbF₂ revealing an increasing distortion with pressure.
