The following automatic conversions were performed:

'_chemical_melting_point' value '87-88.5_C' was changed to '360.9(8)'
- 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^)+(0.0611P)^2^+0.2296P] 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^)+(0.0611P)^2^+0.2296P] where P=(Fo^2^+2Fc^2^)/3'.
