Cambridge Structural Database (CSD) is the world’s repository for small-molecule organic and metal-organic crystal structures and has become an essential resource to scientists around the world. It is continually updated with new structures (>50,000 new structures each year) and with improvements to existing entries.
CSD contains over 800,000 entries from x-ray and neutron diffraction analyses that allows you to create a unique database of accurate 3D structures. Each database entry is enriched with bibliographic, chemical, and physical property information. Learn more.
