International Union of Crystallography

Aims of the IUCr u Promote international cooperation in crystallography u Contribute to the advancement of crystallography in all its aspects, including related topics concerning the non-crystalline states u Facilitate international standardization of methods, of units, of nomenclature and of symbols used in crystallography u Form a focus for the relationship of crystallography to other sciences
