The following automatic conversions were performed:

'_chemical_melting_point' tag was changed to
'_chemical_temperature_decomposition' since the value had been given
as '230-232 deg.C (decomp.)'. The value was changed to '504.1(10)' -
it was converted from degrees Celsius(C) to Kelvins(K), the average
value was taken and precision was estimated.

'_symmetry_cell_setting' value 'Triclinic' changed to 'triclinic'
according to
/home/data/users/saulius/crontab/automatic-downloads/rss-feeds/RSC/lib/dictionaries/cif_core.dic
dictionary named 'cif_core.dic' version 2.4.2 from 2011-04-26.
