The following automatic conversions were performed:

'_chemical_melting_point' value '453-455' was changed to '454.0(10)'
- the average value was taken and precision was estimated.

The following automatic conversions were performed:

'_exptl_crystal_density_meas' value 'not measured' was changed to '?'
- the value is perceived as not measured.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc w =
1/[\s^2^(Fo^2^)+(0.1010P)^2^+0.2377P] 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^)+(0.1010P)^2^+0.2377P] where P=(Fo^2^+2Fc^2^)/3'.
