Can I search on CSD refcodes within ConQuest?


Each CSD entry is identified by a unique Refcode (entry ID) comprising six letters. Some entries also include two digits which identify additional structure determinations, for example, ABACOF03. To retrieve an entry whose Refcode is known simply hit the Refcode (entry ID) button in Build Queries and type the required Refcode into the input box.

It is also possible to search for all occurrences of a particular refcode, for example, to retrieve all structures where the first six letters of the refcode are GLYCIN. Type GLYCIN into the input box and ensure that the Find all Refcodes that begin with query text option is selected.

Note: Due to the way in which Refcodes are assigned, it is not valid to search the CSD using refcode ranges.​
