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.

We need you! If you would like to volunteer to be part of the team and help contribute some of the element pages then drop us an email on with the 'IYPT in Crystals' subject line and we will explain more about the project and how you can contribute and of course how you can feature on our contributors page! Find out more about volunteering here.

The IYPT in Crystals team is also working with expert educators to help others use this resource in education by creating additional worksheets and educational material based on these pages so it can be used in schools, science festivals or uniform groups. Once completed our resources will be available here.

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.
