WebCSD - the on-line portal to the Cambridge Structural Database (CSD)


WebCSD provides easy and convenient access to the wealth of structural knowledge contained in the Cambridge Structural Database (CSD).

If you have access to the CSD-Core then WebCSD can be accessed by going to:


Institutions with site-wide CSD-Core access can search the full CSD from any computer at their site using just a standard web-browser on any desktop, tablet or mobile device, and without the need to install or register any software locally. This ease of access makes the online version of the CSD the ideal platform for introducing 3D structural information into classroom and computational teaching laboratories. Institutions with a limited licence (based on number of users) can access WebCSD by Signing In online and providing their site licence details for up to their allowed number of user log-ins.
In addition to full text and numeric searching, WebCSD allows 2D chemical substructure queries (exact, substructure or similarity) to be defined using an embedded sketcher (CSD Sketcher). This allows non-expert users to locate specific structures of interest, and their analogues, without having to learn the subtleties of substructure searching.

Frequent data updates provide access to the very latest archived CSD structures. In addition, WebCSD users will gain early access to newly published structures. Flagged as 'New structure undergoing enhancement' such entries are added to WebCSD on a continual basis as they are published or deposited as CSD Communications and evolve into full CSD entries following scientific curation by the CCDC's team of Scientific Editors.
