The United Nations has declared 2019 the International Year of the Periodic Table.  Scientists around the world are celebrating with a variety of events.  The CCDC have partnered with the British Crystallographic Association to celebrate the way we know best:  with crystal structures!

Crystals contain different numbers and types of elements from the periodic table ordered in 3 dimensions. The IYPTCrystals project aims to let you see inside those crystals and to celebrate the amazing science that has been made possible through crystallography and the periodic table.

Throughout the year we will be highlighting each element in the Periodic Table with a crystal structure either including or related to that element.  For answers to some common questions about this project, see our FAQ.  To learn about the people behind this project, check out our page of dedicated volunteer contributors

Click through the elements on the table below to learn more about each one!


The Cambridge Structural Database (CSD) is a database of nearly 1 million organic and metal organic crystal structures. The database entries contain many different element types and the diversity of different element types that can been found in these structures has increased over the decades.  This periodic table is colour-coded to show the amount of each element present in the structures of the CSD.
