- Cambridge Crystallographic Database (WebCSD) - from the Cambridge Crystallographic Data Centre (CCDC) is the world's largest repository, for small-molecule organic and metal-organic crystal structures, with more than 900,000 curated entries from x-ray and neutron diffraction analysis. Along with data about the crystal structure, each entry includes chemical/physical property data and associated journal article reference. See WebCSD coverage.
CCB students can access WebCSD two ways:
Cambridge Structural Database System (CSDS) - the full suite of CCDC databases that you download to run on your computer. Includes Conquest for searching CSD, and Mercury for visualization and 3D printing (other databases listed to the right). The "power user" version. To access, you'll need to download and install the software, ask Chemistry Librarian for site and registration codes.
WebCSD - Online access to the Cambridge Structural Database, if you just want to search or browser structures and view the associated crystallographic, chemical, or bibliographic information for each.
