The following automatic conversions were performed:

'_chemical_melting_point' tag was changed to
'_chemical_temperature_decomposition' since the value had been '527
(decomposes)'. The value '527 (decomposes)' was changed to
'527'.

'_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.

'_geom_bond_publ_flag'
value 'Yes' changed to 'yes' according to
/home/saulius/struct/CIF-dictionaries/cif_core.dic dictionary named
'cif_core.dic' version 2.4.1 from 2010-06-29 (21
time).

'_geom_angle_publ_flag' value 'Yes' changed to 'yes'
according to /home/saulius/struct/CIF-dictionaries/cif_core.dic
dictionary named 'cif_core.dic' version 2.4.1 from 2010-06-29 (26
times).
