| 301836 (current) | 2025-08-20 | Add cross-references to PubChem compounds in COD range 4/30/ Each referenced PubChem compound corresponds to the full crystal structure. |
4303037.cif |
| 192782 | 2017-03-02 | cod/ (antanas@echidna.ibt.lt) Correcting misspelt data item names by using the 'cod_correct_tags' script and the replacement file 'data/replacement-values/replacement_tags.lst' from the cod-tools repository (rev. 5004). The correction was mainly focused on removing misspelt versions of the '_publ_contact_author' loop data items. |

| 176432 | 2016-02-14 | cif/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries. |
4303037.cif |
| 129439 | 2015-01-07 | cod/ (robertas@burundukas) Correcting values of _exptl_crystal_density_meas and _exptl_crystal_density_method data items: codsql "select codid from validation where message like '%\\'_exptl_crystal_density_meas\\' value \"not measured\" is %'" -NB \ | codid2file \ | xargs perl -i -pe "s/_exptl_crystal_density_meas\\s+'not +measured'/_exptl_crystal_density_meas ?/i; \ s/_exptl_crystal_density_method\\s+('not +measured'|\\?|none)/_exptl_crystal_density_method ./i" |

| 120081 | 2014-07-12 | Adding DOIs to range 4/30 structures. | 4303037.cif |
| 34330 | 2012-02-24 | cif/4/ Reorganising CIF range 4 into a prefix tree. |
4303037.cif |
| 5312 | 2011-01-03 | cif/ Adding files, updated with the 'cif_fix_enum' program and the cif_core.dic dictionary. The enumerator values were fixed, mostly incorrect case, but also some values that had extra underscores, dashes or spaces. Unfortunately, 22 had non-ASCII characters with the 8-th bit set, and these got incorrectly interpreted as latin1 characters and converted to their UTF8 equivalents by Perl. To fix the structures, however, they need to be redeposited from the original files with the new CIFParser/cif_filter version. |
4303037.cif |
| 1125 | 2010-04-25 | cif/4/ Adding CIFs for the Inorg-Chem-2009_11-24 deposition. |
