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:

At present the standalone CSDSystem applications and databases cannot easily be added to managed Windows computers within this Department by WPKG. This is due to the size of the installed components growing to around 25Gb and therefore the time taken to install them. This makes a distributed installation by WPKG impractical. The system may be able to be accessed on the Managed Cluster Service computers throughout the University & in Colleges.


Instructions for users: 

For managed Windows computers

Please see the note above. We are considering the option to split the databases from the software, making the latter available for installation by WPKG in the future.

For unmanaged computers

For managed Linux computers

Following consultations with Group Computer Representatives toward the end of 2018 we have not distributed the CSD System to managed Linux computers since the 2019 release.

Please refer to the CCDC documentation page for IsoStar Client and contact CCDC Support if you believe you need access to the IsoStar Server software, for which a server installer is available for in-house use, but CCDC would recommend you use their public IsoStar Server.

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.


Licence Details: 

This is proprietary software. The Department has a site licence.
