The following automatic conversions were performed:

'_chemical_melting_point' tag was changed to
'_chemical_temperature_decomposition' since the value had been given
as '400-402 (decomp.)'. The value was changed to '401.0(10)' - the
average value was taken and precision was estimated.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value '1/[\s^2^(F)+0.0016F^2^]' 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)+0.0016F^2^]'.
