The following automatic conversions were performed:

'_chemical_melting_point' value '337-338 K' was changed to '337.5(5)'
- the average value was taken and precision was estimated.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value
'w=1/[\s^2^(F~o~^2^)+(0.1228P)^2^] where P = (F~o~^2^+2F~c~^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^(F~o~^2^)+(0.1228P)^2^] where P = (F~o~^2^+2F~c~^2^)/3'.
