The following automatic conversions were performed:

'_symmetry_cell_setting' value 'Monoclinic' changed to 'monoclinic'
according to the built-in table from CIF Core dictionary named
'cif_core.dic' version 2.4.1 from
2010-06-29.

'_exptl_absorpt_correction_type' value 'MULTI-SCAN'
changed to 'multi-scan' according to the built-in table from CIF Core
dictionary named 'cif_core.dic' version 2.4.1 from 2010-06-29.

  After discussions with the corresponding author T. J. Boyle,
  reassigning this entry as "Personal Communication to COD", and
  replacing the original _chemical_formula_sum with the calculated
  value. Neither originally procided summary formula nor the
  calculated value could be matched against the tables in the
  10.1016/j.poly.2005.03.055 paper.

The following automatic conversions were performed:

'_exptl_crystal_density_meas' value 'not measured' was changed to '?'
- the value is perceived as not measured.
