X-ray diffraction patterns were collected at ID15B high energy beamline of the European Synchrotron Radiation Facility (ESRF, Grenoble, France), using energy of 87 keV
and a PerkinElmer flat panel detector. Data were acquired on randomly-oriented powders packed in polyimide capillaries having a diameter of 1 mm and on empty capillary used for background subtraction. 40 frames of 5 s, corrected for detector’s dark current, were collected for each sample.
