International Union of Crystallography

What International Union of Crystallography does

The International Union of Crystallography (IUCr) is a non-profit international scientific union founded in 1947 and incorporated under Swiss civil law with legal domicile in Geneva, Switzerland; its operational Executive Secretariat is headquartered at 5 Abbey Square, Chester, United Kingdom, led by Chief Executive Officer Dr. A.M. Stanley. The IUCr's stated mission is the international promotion and coordination of crystallography, which it executes through standardization, peer-reviewed publishing, and convening the global structural science community. It is the only International Scientific Union that publishes its own primary research journals, and it curates the internationally adopted Crystallographic Information Framework (CIF), checkCIF validation tools, the imgCIF format for raw diffraction data, and the authoritative International Tables for Crystallography reference publication.

The IUCr's product surface comprises eight primary research journals (Acta Crystallographica Sections A-F, IUCrJ, Journal of Applied Crystallography, Journal of Synchrotron Radiation, and IUCrData), reference volumes and the IUCr/OUP Book Series, the quarterly IUCr Newsletter, and self-serve digital tools including the World Directory of Crystallographers, checkCIF, and imgCIF_creator. Governance is exercised through Adhering Bodies from approximately 52 countries, five Regional Associates (AfCA, ACA, AsCA, ECA, LACA), 24 Scientific Commissions, and triennial Congresses and General Assemblies (27th in Calgary 2026, 28th in Berlin 2029). Recent strategic positioning includes the UNESCO-coordinated International Year of Crystallography 2014, the OpenLabs and LAAAMP capacity-building initiatives, and integration with FAIR data principles for raw diffraction data publication.

Revenue is generated through institutional journal subscriptions and article processing charges for open access publication, recurring Adhering Body membership dues across five categories with voting power aligned to contribution, sales of International Tables (online and print) and IUCr Books, and a three-tier Company Associates Programme whose disclosed sponsors include Bruker, Dectris, Rigaku, Thermo Fisher Scientific, Oxford Cryo, Anton Paar, and STOE. The customer base is structured around academic and research institutions as the primary segment, with secondary segments in industry/corporate research and educators/students. Headcount is in the 11-50 range concentrated in the Chester secretariat; revenue figures are not publicly disclosed and the organization is governed independently with no parent company, venture capital, or private equity ownership.

Core offering

The International Union of Crystallography (IUCr) is a non-profit international scientific union that publishes primary research journals (Acta Crystallographica Sections A-F, IUCrJ, Journal of Applied Crystallography, Journal of Synchrotron Radiation, and IUCrData), maintains the authoritative International Tables for Crystallography reference work, and develops the Crystallographic Information Framework (CIF) standard. It serves the global crystallography community through membership-based national adhering bodies, triennial congresses, scientific commissions, the World Directory of Crystallographers, and corporate sponsorship programs.

Product overview

The International Union of Crystallography operates as a scientific union that publishes its own primary research journals—unique among International Scientific Unions—including Acta Crystallographica Sections A-F, IUCrJ, the Journal of Applied Crystallography, the Journal of Synchrotron Radiation, and IUCrData. The organization maintains the International Tables for Crystallography as definitive reference works and distributes a quarterly IUCr Newsletter. Additionally, IUCr supports the crystallographic community through the CIF (Crystallographic Information Framework) data standard with associated validation tools like checkCIF, the World Directory of Crystallographers, and educational resources including teaching pamphlets and the IUCr/OUP Book Series.

Direct peers

• International Union of Geodesy and Geophysics (IUGG): A peer international scientific union with similar Adhering Body governance, commissions, and triennial assemblies, providing a directly comparable governance and funding model.
• International Centre for Diffraction Data (ICDD): A scientific associate of IUCr that maintains the Powder Diffraction File and serves the diffraction community with reference databases, making it a natural peer in crystallographic data products and standards.
• International Astronomical Union (IAU): A peer international scientific union with comparable membership structure, national adhering bodies, and standards/nomenclature responsibilities, but focused on astronomy rather than crystallography.
• Cambridge Crystallographic Data Centre (CCDC): Operates the Cambridge Structural Database and develops validation tools (checkCIF-adjacent) widely used by crystallographers. A direct peer in crystallographic data standards, structure validation, and community-facing services.
• International Union of Pure and Applied Chemistry (IUPAC): A peer international scientific union that develops nomenclature, standards, and reference data for chemistry, with similar membership-based governance, publishing activities, and Adhering Body structure spanning dozens of countries.
• Worldwide Protein Data Bank (wwPDB): A scientific associate of IUCr and the primary archive for macromolecular structures. Directly comparable as a community-governed structural-biology data repository with overlapping users and validation standards.

Broad incumbents

• American Chemical Society (ACS): A larger learned society publishing primary research across chemistry and adjacent fields. Comparable to IUCr as a member-governed publisher but with a much broader disciplinary scope and revenue base.
• Royal Society of Chemistry (RSC): A major learned society and publisher in chemistry that publishes primary research and reference works and operates across a broader portfolio than IUCr, with comparable member-driven publishing and standards roles.
• Springer Nature: A leading commercial publisher of scientific journals and reference works, including titles in crystallography and structural science. Comparable as a publisher and standards-adjacent content provider, though commercially and not member-governed.

Emerging players

• International Organization for Crystal Growth (IOCG): A scientific associate of IUCr focused on crystal growth, overlapping with one of IUCr's commissions. Comparable as a smaller international association serving part of the same research community.
