Welcome to the
International Union of Crystallography

The IUCr is an International Scientific Union. Its objectives are to promote international cooperation in crystallography and to contribute to all aspects of crystallography, to promote international publication of crystallographic research, to facilitate standardization of methods, units, nomenclatures and symbols, and to form a focus for the relations of crystallography to other sciences.

  • Crystallographers unite to tackle coronavirus

    With stories about coronavirus dominating the news, we report that crystallographers around the world are making strong contributions to the efforts to find a vaccine and advance therapeutics.

  • Temporary job opportunities for scientists fleeing Ukraine

    Within the first month of the Russian invasion of Ukraine, thousands of scholars fled the country. The global scientific community reacted quickly and created numerous opportunities in their institutions and labs. In March 2022, the crowd-funded initiative #ScienceForUkraine collected more than 1500 offers of support from 50 countries, with the potential to help more than 3000 displaced Ukrainian scholars. If you are affected, please see the list of opportunities here.

  • Jill Trewhella wins 2022 Guinier Prize

    We are delighted to announce that Jill Trewhella (University of Sydney, Australia) is the recipient of the 2022 Guinier Prize. The award recognises Professor Trewhella's achievements, positive influence and strong contributions to the thriving field of small-angle scattering.

  • Mamannamana Vijayan (1941-2022)

    We are sad to report that the eminent structural biologist Mamannamana Vijayan, NASI Senior Scientist Platinum Jubilee Fellow, Molecular Biophysics Unit, Indian Institute of Science, Bangalore, died on 24 April 2022 at the age of 80. Professor Vijayan was closely connected with the IUCr having served on the IUCr Commissions of Small Molecules (1984–1990) and Biological Macromolecules (1987–1993, Chair 1993–1996) and as a Co-editor of Acta Cryst. B, C and D from 1992 to 2005.

  • Distinguished Lectures on Quantum Crystallography and Complementary Fields

    The next two online lectures in the monthly series of Distinguished Lectures on Quantum Crystallography and Complementary Fields will be presented on Thursday 28 April 2022 at 16:00 CET.

  • Call for nominations for the thirteenth Ewald Prize

    The International Union of Crystallography is pleased to invite nominations for the Ewald Prize for outstanding contributions to the science of crystallography. The thirteenth Prize will be presented at the Melbourne Congress in August 2023.

  • IUCr denounces the invasion of Ukraine

    The International Union of Crystallography (IUCr) is greatly dismayed by the invasion of Ukraine and is concerned about its impact for the rest of the world. The IUCr stands in solidarity with the international scientific community as we are concerned for the well-being and life of all Ukrainian people. We stand by their side. The IUCr seeks ways to serve all its members worldwide during this difficult time; it declares its support for the rights and freedoms conveyed in the Universal Declaration of Human Rights for all people.

    The IUCr condemns all wars, and calls for a halt to hostilities and for a peaceful end to this crisis. We have suspended publication fees for our journals for authors based in the Ukraine (for more details contact support@iucr.org).

The best in crystallographic research

Uniquely among International Scientific Unions, the IUCr publishes its own primary research journals. Acta Crystallographica Sections A–F, IUCrJ, Journal of Applied CrystallographyJournal of Synchrotron Radiation and IUCrData communicate the highest quality peer-reviewed research findings across the many scientific areas to which crystallography is relevant.
