| 301863 (current) | 2025-08-22 | Add cross-references to PubChem compounds in COD range 7/20/ Each referenced PubChem compound corresponds to the full crystal structure. |
7203901.cif |
| 202017 | 2017-10-14 | cif/ Marking COD entries in range 7 that are known to be related to ChemSpider entries using the _cod_related_entry data loop. |

| 180370 | 2016-03-26 | cif/7/20/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 7/20/39. |
7203901.cif |
| 120443 | 2014-07-15 | Adding 17924 DOIs guessed from source file names. | 7203901.cif |
| 35909 | 2012-02-26 | cif/7/: reorganising range 7 into a prefix-directory tree. | 7203901.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. |
7203901.cif |
| 3890 | 2010-12-07 | cif/7/ Adding CIFs with data extracted from New-J-Chem-2004-2000/, Org-Biomol-Chem-2004-2000/ and RSC-2004-2000/. |
