CCDC National Affiliated Centre - Canada

The National Affiliated Centre (NAC) Canada operates on behalf of the Cambridge Crystallographic Data Centre (CCDC) and is hosted by the Department of Chemistry at the University of Guelph.
We distribute licences of the Cambridge Structural Database (CSD) and affiliated software, and provide support to Canadian users. CSD contains small molecule structures containing organic carbon. It is the largest of crystallographic databases; in June 2019, the database reached 1 million structures. As of January 2024, more than 1,300,000 structures are available.

Licensing
Since 2014, the licences for Canadian users are distributed through Guelph. Contact Dmitriy if you want to acquire or change your current licence type. There are three types of licences:
- Researcher licence (installation of the database on TWO computers plus two individual logins for WebCSD).
- Group licence (installation on up to SIX computers plus six logins for WebCSD).
- Campus licence (250 installations and WebCSD access within your campus and additional six WebCSD logins).
Multi-year licences may be negotiated upon request.
Please contact the Finacial Clerk regarding payments.
Your current licence is valid until the end of the year. Notify us ahead of time if you would like to renew. If you hold a multi-year licence, it will be renewed in the new year automatically.
For a licence renewal, contact Dmitriy with the type of licence you would like to have for the year. See below the description of licence types. Once your site licence is activated, you will receive a link plus instructions for the database renewal. We will invoice you according to your licence type and term.
All updates and instructions are available from the CCDC website.
