The following automatic conversions were performed:

'_chemical_melting_point' value '110-112 deg. C' was changed to
'384.1(10)' - it was converted from degrees Celsius(C) to Kelvins(K),
the average value was taken and precision was
estimated.

'_symmetry_cell_setting' value 'Orthorhombic' changed to
'orthorhombic' according to
/home/saulius/struct/CIF-dictionaries/cif_core.dic dictionary named
'cif_core.dic' version 2.4.2 from 2011-04-26.
