 Changing _atom_site_fract_y value for atom 'Al(5)' from '2x' to '.499(6)'. 
 For the changes the original paper with doi 10.1107/S010827019400377X was 
 consulted.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value '1/\s^2^(|F|)' was changed to
'calc'. New tag '_refine_ls_weighting_details' was created. The value
of the new tag was set to 'w = 1/\s^2^(|F|)'.
