At CCDC we understand the power of quality data, and strong collaborations.

That is why we have built partnerships with other trusted scientific data repositories around the world.

Through these partnerships we want to ensure we adhere to FAIR data principles and that CSD users, publishers and other interested parties can easily access relevant, quality data across platforms and providers to support their work.

We are proud to be a CoreTrustSeal certified data repository, and look to partner with organisations who understand the importance of high quality data as we do.


This list details current links between the Cambridge Structural Database (CSD) and other data sets.

If you are interested in partnering with us please get in touch here.


We also partner with other software providers to allow scientists to access and use our data in a range of different ways. See a list of our software partners here.



The ChEMBL database is home to 2D structures, calculated properties and abstracted bioactivities of small molecules. It houses 1.9 million structures and is managed by EMBL-EBI, the European Molecular Biology Laboratory's European Bioinformatics Institute.

In 2020 the CCDC announced their partnership with ChEMBL as part of the BioChemGraph project.

FIZ Karlsruhe

FIZ Karlsruhe are the curators of the ICSD - the Inorganic Crystal Structure Database.

Since 2018 the CCDC and FIZ Karlsruhe have offered free, unified deposition of crystal structure data so that scientists and pubishers can access quality data from both sources quickly and easily.

Learn more about the partnership here, access structures from both databases here, or deposit your structure to both databases here.



The International Centre for Diffraction Data (ICDD) manages the curation, publication and distribution of X-ray powder diffraction data.

In 2020 the CCDC and ICDD announced their partnership, which will see the ICDD calculate and publish diffraction patterns (including atomic co-ordinates) from structures found in the CSD.

Learn more about the partnership here.



The Protein Data Bank in Europe curates crystal structures of proteins. It is managed by EMBL-EBI, the European Molecular Biology Laboratory's European Bioinformatics Institute.

In 2020 the CCDC and PDBE announced their partnership on the BioChemGraph project, to bring together chemical and biochemical data in one simple platform.
