An International Scientific Union

Formally admitted to the International Council of Scientific Unions (ICSU) on 7 April 1947, the IUCr remains committed to its goals of promoting international cooperation in crystallography and advancing the science, promoting international publication of crystallographic research, facilitating standardization of methods, units, nomenclatures and symbols, and forming a focus for the relations of crystallography to other sciences. As more and more new approaches to exploring the structure of matter at the atomic scale develop, the IUCr embraces a growing range of novel and exciting scientific fields.

International Union of Crystallography

The IUCr is a scientific union adhering to the International Science Council (ISC). 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.

The IUCr fulfils these objectives by publishing in print and electronically primary scientific journals through Crystallography Journals Online, the series of reference volumes International Tables for Crystallography, distributing the quarterly IUCr Newsletter, maintaining the online World Directory/Database of Crystallographers, awarding the Ewald Prize and the Bragg prize, implementing outreach initiatives and organising the triennial Congress and General Assembly.
