Cambridge Structural Database (CSD), 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 analyses. Along with data about the crystal structure, each entry includes chemical/physical property data and associated journal article reference.
UC San Diego faculty, staff and students can access CSD two ways:
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, which you can access here along with the site and registration codes (VPN required if off campus).
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.
CSDS includes the following programs, with detailed user guides and (in some cases) tutorials available for each. After the initial software download, there will be period updates to the data and software you'll need to download. Mercury and Hermes are set to check for updates automatically.
