The following automatic conversions were performed:

'_chemical_melting_point' value '68 - 69' was changed to '68.5(5)' -
the average value was taken and precision was estimated.

'_symmetry_cell_setting' value 'Orthorhombic' changed to
'orthorhombic' according to the built-in table from CIF Core
dictionary named 'cif_core.dic' version 2.4.1 from 2010-06-29.
