International Union of Crystallography


The scientific work of the IUCr is conducted through its Commissions.

Each Commission page contains Terms of Reference, details of members and consultants and links to annual and triennial reports. A link is also provided to the web pages maintained by the Commission (where available).

Contacting Commissions

Each non-publishing Commission has a global email address. Emails sent to this address will go to all members and consultants of the Commission and to the member of the Executive Committee with special responsibility for the Commission. Those applying to the Meeting Support Committee for support of a meeting and seeking support of a Commission for their application should contact the relevant Chair.
