a–f High-pressure synchrotron X-ray diffraction under various pressures up to 11.9 GPa at room temperature. g, h Pressure dependence of lattice parameters (a, b, c, volume V) and the relative shrinkage of lattice parameters a/a0, c/c0 and the axis ratio a/c. In g, the Birch–Murnaghan (B–M) isothermal equation of state was adopted to fit the pressure dependence of volume V(P). A clear slope change in a/a0, c/c0, and a/c can be found around 7 GPa.
