The following automatic conversions were performed:

'_chemical_melting_point' value '423-427 K' was changed to '425(2)' -
the average value was taken and precision was
estimated.

'_atom_site_thermal_displace_type' tag value 'Uij' was
replaced with 'Uani' value 31 time.

The following automatic conversions were performed:

'_exptl_crystal_density_meas' value 'not measured' was changed to '?'
- the value is perceived as not measured.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'w =
1/{[\s~cs~(F^2^)+1.03F^2^]^1/2^-|F|}^2^' was changed to 'calc'. New
tag '_refine_ls_weighting_details' was created. The value of the new
tag was set to 'w = 1/{[\s~cs~(F^2^)+1.03F^2^]^1/2^-|F|}^2^'.
