The Cambridge Crystallographic Data Centre accepts depositions of
crystal structure data from X-ray
and neutron diffraction studies, and from powder studies using a constrained refinement, for:
organic compounds
metal-organic compounds
Data depositions with the CCDC are of two main types:
Pre-Publication: your structure(s) are being submitted for publication in a journal
Private Communications to the CSD: your structure(s) are not intended for
publication, but you wish them to be available to other scientists through the CSD
However, data for structures which have already appeared in a journal and are not yet in the CSD are always welcome. Depositions should include the list of authors and the full journal reference. An electronic or
printed copy of the journal article is appreciated, especially for the less-common journals.
Note that data for Acta Crystallographica and Zeitschrift für Kristallographie - New Crystal
Structures are received from the Editorial offices.
The electronic CIF format should be used for all depositions.
If this causes significant problems, please contact
to discuss other possible formats. However, most major journals now require cifs and the notes for authors should be consulted.
On receipt, all depositions are stored in the secure and separate CCDC Supplementary
Data Archive. After publication, deposited structures will be processed to the main
distributed CSD, and the original deposited data will also be made freely available
to all scientists on request, for bona fide research purposes.
Data for other compounds are collected by the databases shown below.
They should be contacted via their websites for further information.
