Cambridge Structural Database - UMass Dartmouth Information For Access

Cambridge Structural Database (CSD)

The CSD is a repository of small-molecule organic and metal-organic crystal structures. Containing the results of over half-a-million x-ray and neutron diffraction analyses this is a unique database of accurate 3D structures.  CSD provides a comprehensive and retrospective coverage of the published literature. The CSD is continually updated with new structures and with improvements to existing entries. The CSD System also comprises software for database access, structure visualization and data analysis, and structural knowledge bases derived from the CSD.

There are two methods for accessing the Cambridge Structural Database System (CSDS):

1. WebCSD (Cambridge Structural Database/CSD)  - This the CSD web-based version available here and on the library’s Articles & Databases web page.

2. Local Computer Install Version - Install the CSD program (database, software and additional components) on your local UMassD computer. Additional features are available via this client software. Use the Request Form Link below to receive more CSD information and specific information and links for downloading the appropriate CSD program components.

NOTE: Not all program components are available for all computer operating systems. See the Cambridge Crystallographic Data Centre site for more information about these program components. Please be aware that the complete packages are multiple Gigabytes in size. You will need the UMassD site and UMassD confirmation codes to register the product after it is installed and for the quarterly updates issued by Cambridge Crystallographic Data Centre.
