Isothermal compressibility of MgCl2·7H2O at 298 K obtained from in-situ powder X-ray diffraction. The sample pressure (p) was derived from the equation of state (EoS) of ice VII (Klotz et al., 2017BB27). MILEOS fitting curves (solid lines) are derived from data from both compression and decompression. Linear compressibilities along principal axes (ni, where i = 1, 2, 3) as well as their sum as the bulk compressibility (nV) and inclination angle of β1 against the a axis (θ) derived from the derivatives of the fitted MILEOS curves of the lattice parameters are also described in the solid curves. The linear fits of the compressibilities are also shown in the dashed curves.
