The majority of data archives for chemistry datasets are specifically for structural data, whereas datasets underpinning publications currently tend to be published either in the interdisciplinary data archives (particularly Dryad or figshare), or as supplemental material to journal articles.
The list of structural databases provided in this guide are those that are recommended by major UK funding bodies or by journal publishers. You can search re3data or FAIRSharing for a full list of research data archives publishing chemistry datasets.
The Royal Society of Chemistry has published recommendations for the use of data archives for data underpinning publications within their journals. Their recommended archives are listed below.
