Welcome to the Open Access Crystallography Resource Portal

Crystallography Open Database: Contains more then 360,000 small molecules and small to medium unit cell crystal structures (including minerals but excluding biopolymers). Main sites www.crystallography.net (in France) and cod.ibt.lt (in Lithuania). Less frequently updated mirrors cod.ensicaen.fr (in France), qiserver.ugr.es/cod (in Spain), nanocrystallography.org and nanocrystallography.research.pdx.edu/search/codmirror/ (in North America).



Portland State University's Nano-Crystallography Group: nanocrystallography.research.pdx.edu hosts small educational open access databases of common crystal structures (e.g. EDU-COD and CMD). The Wiki Crystallography Database, to which we invite you to contribute, offers over 8,000 entries on minerals.


Full Profile Search Match: A "Rietveld like" fitting procedure is utilized to quantify the crystal phase content as well as the average crystallite sizes and strains from a two column plain text input file that you need to create from the output of your powder X-ray diffractometer. The Crystallography Open Database (COD) provides the necessary crystal structure information. Since the basis of these quantifications is the automatic identification of the crystal phases in your crystal powder sample, it is all the more important that the scientific community makes the COD as complete as possible (by e.g. uploading their own CIFs or contributing to that project by other means). http://cod.iutcaen.unicaen.fr/
