The following automatic conversions were performed:

'_chemical_melting_point' value '136-138' was changed to '137.0(10)'
- 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.
