|---|---|---|---|
| 301853 (current) | 2025-08-22 | Add cross-references to PubChem compounds in COD range 7/10/ Each referenced PubChem compound corresponds to the full crystal structure. |
7105152.cif |
| 176453 | 2016-02-16 | cif/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in range 7. |
7105152.cif |
| 106664 | 2014-03-15 | cif/ (saulius@koala.ibt.lt) Adding DOIs to the rest of the Chem. Comm. files. Some of these files have author names differing from PubMed in diacritics (either diacritics are omitted or we have encoding problems); or they have a year difference of 1. However, since first pages always match and author names are variants of each other, I assume that DOIs are assigned correctly. |

| 35909 | 2012-02-26 | cif/7/: reorganising range 7 into a prefix-directory tree. | 7105152.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. |
