The following automatic conversions were performed:

'_chemical_melting_point' tag was changed to
'_chemical_temperature_decomposition' since the value had been given
as 'd. 260(5)_C'. The value 'd. 260(5)_C' was changed to '533(5)' -
it was converted from degrees Celsius(C) to Kelvins(K).

'_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.0711P)^2^+0.0000P] where P=(Fo^2^+2Fc^2^)/3' was
