The following automatic conversions were performed:

'_chemical_melting_point' value '160-161' was changed to '160.5(5)' -
the average value was taken and precision was
estimated.

'_symmetry_cell_setting' value 'Triclinic' changed to
'triclinic' according to
/home/saulius/struct/CIF-dictionaries/cif_core.dic dictionary named
'cif_core.dic' version 2.4.1 from 2010-06-29.
