(a) Synchrotron radiation x-ray diffraction patterns of PdSn₄ under pressures (λ = 0.4133 Å). The XRD pattern upon decompression back to 0.0 GPa is denoted by DP. (b) The refinements at (b) 0.5 GPa and (c) 44.5 GPa were performed by using the RIETICA program with the Le Bail method. (d) Pressure dependence of the refined lattice parameters. (c) The empty symbols stand for unit volume. The volume versus pressure data was fitted by the third-order Birch–Murnaghan formula (solid red line).
