IYCr2014 was a year-long series of events and initiatives celebrating the first hundred years of structure determination using X-ray diffraction. With an emphasis on educational and public outreach, it also acknowledged the growth in our understanding of the nature and internal structure of crystals, from Kepler's appreciation of the symmetries of snowflakes 400 years ago, to modern scientific and technological advances built on our detailed understanding of the structure of matter in the solid state.

Sponsored by the United Nations Educational, Scientific and Cultural Organisation (UNESCO) and the International Union of Crystallography (IUCr), and with the support of dozens of educational, scientific and cultural partners, IYCr2014 saw hundreds of events staged across the world. A dedicated website,, records the great variety of activities and initiatives that were begun in 2014, many of which continue under the motto "Crystallography matters ... more!
