Cambridge Crystallographic Data Centre

CCDC is a world-leading expert in structural chemistry data, software, and knowledge for materials and life sciences research and applications. Each structure in the CSD undergoes extensive validation and cross-checking through an automated workflow, along with manual curation by expert chemists and crystallographers. This means you can trust that all data in the CSD is accurate, consistent, and of high quality. Researchers are able to directly publish unpublished, confidential, and unknown data via the CSD. As a result, the CSD contains data that is unavailable elsewhere.
