Data should be preferably in CIF format and contain unit cell parameters, coordinates, a brief literature reference and, when available, atomic displacement parameters (as well as temperature and/or pressure if different from room conditions, etc). In addition to using the CIF format for submission of data, please use zip compression for files greater than 1Mb. If you have a large number of structures in some format other than CIF, we can attempt to find a way to convert that format into CIF. Please contact cod@cristal.org.

Alternately, condensed data can be deposited in the very simple REF format.
