| 203286 (current) | 2017-11-17 | cif/2/10/10/ Correcting the date in the _cod_depositor_comments data item in entries 2101052, 2101053, 2101054, 2101055, 2101056. |
2101052.cif |
| 203283 | 2017-11-17 | cif/2/10/10/ Correcting the z coordinate of the 'O' atom in entries 2101052, 2101053, 2101054, 2101055, 2101056 by changing it from '.0' to '0.25' after consulting the original publication. |
2101052.cif |
| 203281 | 2017-11-17 | cif/2/10/10/ Upon a secondary inspection it was discovered that an incorrect Hermann-Mauguin space group symbol ('R -3 c :R' instead of 'R -3 c :H') had been assigned during the previous maintenance change in entry 2101052. The space group symbol and the associated space group information has been updated accordingly. |
2101052.cif |
| 201972 | 2017-10-13 | cif/ Marking COD entries in range 2/10 that are known to be related to ChemSpider entries using the _cod_related_entry data loop. |
2101052.cif |
| 176768 | 2016-02-20 | cif/2/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/10. |
2101052.cif |
| 176428 | 2016-02-13 | Replaced deprecated COD CIF data names with their more modern alternatives. The _cod_cif_authors_sg_Hall and _cod_cif_authors_sg_H-M data items were renamed to _cod_original_sg_symbol_Hall and _cod_cif_authors_sg_H-M respectively. |
2101052.cif |
| 131882 | 2015-02-16 | cif/2/10/10/ (antanas@koala.ibt.lt) Adding missing '_cell_length_b' tag and value after consulting the original paper and changing '_symmetry_space_group_name_H-M' tag value from 'R -3 c {rhombohedral axes}' to 'R -3 c :R' for CIF 2101052. |
2101052.cif |
