Cambridge Structural Database System

Thank you for using the Cambridge Structural Database (CSD). The CSD is a world leading comprehensive collection of small-molecule organic and organometallic crystal structures. All of these crystal structures have been analysed using X-ray or neutron diffraction techniques. The CSD contains crystal structures for over 700,000 organic and organometallic compounds which can be queried via a wide range of associated software packages.

The Chemical Database Service (CDS) provides access to the CSD in two ways.

WebCSD

WebCSD is a browser-based interface that allows users to easily search the CSD, accessible via PSDS below:

Access will automatically be granted to users on UK academic networks. (If you are asked to login while on your academic network, please let us know.)

If you access WebCSD from outside of your academic network, you will be prompted to login either using PSDS username and password. If you do not have a PSDS username and password, you can create an account here.

CSD Remote Desktop

Using the CSD Remote Desktop you can connect to a computer with various software packages available for browsing the CSD. These packages are described in detail on the About page.

Your request for a CSD Remote Desktop username and password is currently being processed; we will get back to you as soon as possible at the email address you supplied on the Terms and Conditions page.

Once you receive your CSD Remote Desktop username and password you will be able to use them to access the CSD Remote Desktop from any location. For more information about the software available for use on the CSD Remote Desktop, please see the About page.

Please note that your PSDS username and password (used to access web-based PSDS services from outside your institution are NOT the same as your CSD Remote Desktop username and password (used to access the CSD Remote Desktop from any location).

If you are experiencing difficulties accessing any PSDS service, please get in touch support@psds.ac.uk for more information.
