The following automatic conversions were performed:

'_chemical_melting_point' value '281-283 C' was changed to
'555.1(10)' - 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:

'_refine_ls_weighting_scheme' value 'calc w= 4F^2^/[\s^2^) +
(0.02F^2^)^2^]' was changed to 'calc'. New tag
'_refine_ls_weighting_details' was created. The value of the new tag
was set to 'w= 4F^2^/[\s^2^) + (0.02F^2^)^2^]'.
