This month marks 10 years since the CCDC began formally accepting experimental structure factor data alongside crystallographic information files (CIFs) for deposition of structures to the CSD. The change came about following the lead and advice of the International Union of Crystallography (IUCr), whose journals have long required authors to provide structure factor data for published crystal structures. Structure factors, as well as other experimental information, are important as they can be used to describe the distribution of electron density in the structure and enable users to further validate a structural model. This also helps make your data more FAIR (Findable, Accessible, Interoperable and Reusable).
