The Cambridge Structural Database (CSD) is a highly curated and comprehensive resource for crystal structures. Established in 1965, the CSD is the world’s repository for small-molecule organic and metal-organic crystal structures. Containing over 900,000 entries from x-ray and neutron diffraction analyses, this unique database of accurate 3D structures has become an essential resource to scientists around the world.

Components of CSD System are: 

CSD The World repository of small molecule crystal structures

ConQuest Search and retrieve data from the CSD

IsoStar A knowledge-based library of intermolecular interactions

WebCSD Access newly published structures online

Mercury Visualise and analyse CSD data

PreQuest Build searchable databases of in-house crystal structures

Mogul Validate molecular geometry

CSD Python API Use the CSD System programmatically

The CSD is installed on the computer in Prof. Janet Hunting's lab.
