The following automatic conversions were performed:

'_chemical_melting_point' value '339-340' was changed to '339.5(5)' -
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^)+(
0.0728P)^2^+0.0515P] 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^)+( 0.0728P)^2^+0.0515P] where
P=(Fo^2^+2Fc^2^)/3'.
