The following automatic conversions were performed:

'_chemical_melting_point' value '272 - 273 C' was changed to
'545.6(5)' - it was converted from degrees Celsius(C) to Kelvins(K),
the average value was taken and precision was
estimated.

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

'_geom_bond_publ_flag'
value 'Y' changed to 'y' according to
/home/saulius/struct/CIF-dictionaries/cif_core.dic dictionary named
'cif_core.dic' version 2.4.1 from 2010-06-29 (11
times).

'_geom_angle_publ_flag' value 'Y' changed to 'y' according
to /home/saulius/struct/CIF-dictionaries/cif_core.dic dictionary
named 'cif_core.dic' version 2.4.1 from 2010-06-29 (16
times).

'_geom_torsion_publ_flag' value 'Y' changed to 'y' according
to /home/saulius/struct/CIF-dictionaries/cif_core.dic dictionary
named 'cif_core.dic' version 2.4.1 from 2010-06-29 (16 times).
