The following automatic conversions were performed:

'_chemical_melting_point' value '165-167' was changed to '166.0(10)'
- 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.
