2022.2 released July 2022

Once you've downloaded CSD you can update as new releases come out. See the below link or contact Lindsay Decker for update instructions.


A big part of studying molecular structures is viewing them. The Cambridge Crystallographic Data Centre (CCDC) maintains and curates the Cambridge Structural Database, where you can find data on and visualizations of crystal structures as well as active molecules like proteins.

As a UMaine affiliate you can use the web-version of the Cambridge Structural Database anytime, or you can download the Cambridge Structural Database package on your device for full use of the tools available. Contact Lindsay Decker for the activation keys and other information required to download.

This page is intended to provide information and easy access to the Cambridge Structural Database, but please see our Additional Crystal Data Sources page for other available tools.

The Cambridge Structural Database (CSD)

The Cambridge Structural Database (CSD) itself is a collection of small molecule crystal structures contributed to by scientists all over the world. There are a number of tools you can access when you download the CSD package through UMaine that can provide further analysis and create 3-D visualizations of these structures. This is a list of the programs you can download onto your device, what they do, and links to more information about them:

The following is a list of additional resources from the CCDC. These are either accessible online or need to be downloaded onto your device. Contact Lindsay Decker if you have any questions.
