| 20519 | 2011-06-11 | smi/* and cif/* Adding SMILES for all structures with nel=1 in the mysql entries, supossed to be pure elements. For most of them, just the element symbol remains since SMILES strings and substructure search makes no sense for compact packed structures. Only for molecularly defined substances (for example cyclosulphur moieties) a proper SMILES string has been defined. This does not add too much funcionality to substructure search but flags a large number of structures as "SMILES done". Some of them were found to be not pure elements (carbides, boranes, hydrocarbons) but were added anyway. CIF files and SQL entries have been fixed for these as well as for other with obviously wrong formulas. |
