The following automatic conversions were performed:

'_chemical_melting_point' value '437-440 K' was changed to
'438.5(15)' - 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^)+(0.0339P)^2^+0.3258P] 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
