Tag _atom_site_attached_hydrogens with values N = 3, C = 2, else = 0 was added. As a result, calculated summary formula contains the correct amount of hydrogens. 2. Two atoms were removed, as they seem to be symmetric equivalents of Al1 and F3: Al1A* Al 0.6756(9) 0.50000 0.0223(5) 0 F3A* F 0.500(4) -0.249(8) 0.001(1) 0 As a result, amount of Al and F in the calculated summary formula is now correct. Moreover, symmetry reconstruction does not result in bumps (distance between atoms = 0) any more. 3. Tag _refine_ls_R_factor_gt was replaced by more relevant tag from powder diffraction CIF dictionary. Tags _pd_proc_ls_prof_wR_factor and _pd_proc_ls_prof_wR_expected were added with data from original publication.
