Synchrotron X-ray diffraction (XRD) studies have been performed at BW5 (λ = 0.1475676 Å) and B2 (λ = 0.68805 Å and λ = 0.69797 Å) beamlines of the DORIS III storage ring (HASYLAB-DESY) at room temperature. PowderCell 2.4 and DatLab 1.34 software were used to analyze the diffraction data. The details of the measurements and data processing are described in our previous publications .
