The following automatic conversions were performed:

'_chemical_melting_point' value '72.5-73.5_C' was changed to
'346.1(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:

'_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.0428P)^2^+0.5611P] 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^)+(0.0428P)^2^+0.5611P] where P=(Fo^2^+2Fc^2^)/3'.
