The following automatic conversions were performed:

'_chemical_melting_point' value '360K' was changed to '360' - the
value should be numeric and without a unit
designator.

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