Rotational phase transitions in antifluorite-type osmate and iridate compounds

-In the folder "SC_XRD" are gathered the average integrated intensities (m90 file) and the cif file resulting from refinements with anharmonic ADPs for all compounds at all temperatures. The two refinements for K2OsBr6 in the low symmetry phases are performed with harmonic ADPs. -In the folder "Fig2_maps" are the precession maps shown in Fig2: original binary .sfrm raw data file and .png images are included. -In the folder "RSD_maps" are the residual scattering density maps in the original .eps format generated by JANA2020 (Fig.3 and Fig.4) -Folder "Fig5_script" contains the matlab code to generate Fig.5 -In the folder "Appendix" A are gathered the ".dsn" graphics source file shown in Appendix A. Raw data can be found after the header line: "1 3 xxx 102 0.15 0.02 900 1 0 0.001 900 0 0 0"
