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 0.6749(2) 0.50000 0.0344(1) F3A* F 0.5047(9) -0.245(1) -0.0049(4) 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.
