LOFHOF ImageThe Cambridge Structural Database is an incredible community achievement as for over fifty years crystallographers have shared the results of every published crystal structure with the CCDC – allowing us to share them with the world. The CCDC is committed to enabling everyone to benefit from the world’s comprehensive and up-to-date database of crystal structures.

Frank H. Allen International Research and Education Programme Education

The Cambridge Crystallographic Data Centre (CCDC) is dedicated to advancing structural chemistry around the world and established the Frank H. Allen International Research and Education Programme (FAIRE) to help support research and education in underrepresented communities. FAIRE award grants cover the cost of campus-level access to CSD-Enterprise for three years for researchers in parts of the world with demonstrable need.

The CCDC is a research institution which is dedicated to the advancement of chemistry and crystallography. By compiling and distributing the Cambridge Structural Database (CSD), (the world's repository of experimentally determined organic and metal-organic crystal structures) the CCDC is the custodian of an invaluable source of data for the scientific community and from which new research tools can be developed.

Training and Educational Resources


The wealth of information contained within the Cambridge Structural Database (CSD) extends far beyond a collection of crystal structures. Knowledge derived from these materials informs much of chemistry, biochemistry, and biology. Chemical and structural concepts are often difficult to grasp without real world, interactive examples for students to explore.

Check out our Training and Educational Resources, here.

CSD Communications

CSD Communications is a collection of small molecule crystallographic data which has been shared by depositors through the Cambridge Structural Database (CSD) without an associated scientific article.

CCDC Annual 3D Print Contest

We want the whole community to know how easy and fun it is to create an experimentally accurate 3D printed molecules of any part of a crystal structure using our visualisation and analysis tool Mercury.

Find out how to get involved and the results from past winners, here.
