The Cambridge Structural Database is the world repository of small molecule organic and metal-organic crystal structures. The Cambridge Structural Database (CSD) is the central focus of the CSDSystem, which also comprises software for database access, structure visualisation and data analysis, and structural knowledge bases derived from the CSD.


All existing academic users of the CSD-System also have access to all other CCDC software with the CSD-Enterprise suite.

WebCSD can be accessed by going to:

The standalone CSDSystem applications can easily be added to managed Windows computers within this Department via WPKG, and can also be accessed on the Managed Cluster Service computers throughout the University & in Colleges.

CSD-System Data & Software Updates

If you have installed the CSD-System yourself on an unmanaged computer following our notes above (i.e. you do not run the software on a Windows desktop where it was installed by WPKG) you can download interim software and data updates during the annual release cycle (approximately every 3 months) from to keep CSD System software and your copy of the CSD database more current between each major release.
