The following automatic conversions were performed:

'_chemical_melting_point' value '115-116 \%C' was changed to
'388.6(5)' - it was converted from degrees Celsius(C) to Kelvins(K),
the average value was taken and precision was estimated.

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 'calc w =
1/[\s^2^(Fo^2^)+(0.0630P)^2^] where P=(Fo^2^+2Fc^2^)/3' 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^(Fo^2^)+(0.0630P)^2^]
where P=(Fo^2^+2Fc^2^)/3'.
