Fig. 3. Pawley fit to the diffraction patterns of compound 1 recorded at ambient pressure (a) and at 0.075(10) GPa (b). Diffractograms were recorded using a monochromatic X-ray beam with λ = 0.41334 Å. The very broad peak (centered at ∼4.4°) underneath the Bragg peaks is attributed to the diffuse scattering from the pressure transmitting fluid FC-70. Crystallographic parameters are listed in Table 1.
