MedeA COD GUI - An Open-Access Collection of Crystal Structures

With the MedeA ®[1] COD GUI, you have rapid access to atomic structures of the Crystallography Open Database (COD), the fastest growing collection of organic, inorganic, metal-organics compounds, and mineral compounds.


The MedeA COD GUI is fully integrated with MedeA InfoMaticA to provide crystal structure data from COD

Key Benefits

  • Quick and efficient structure search and retrieval
  • Full integration with all MedeA modules

Number of records by constituent count that can be accessed via the MedeA COD GUI

COD started in March 2003, and already encompassed around 10,000 structures in 2004. In 2014, within 11 years, COD accumulated over 250,000 structures. Since then, more than 35,000 have been added to COD each year. COD is recommended by scientific journals to deposit crystallographic data.

With the MedeA COD GUI, you have full access to all COD structure data records and can fully leverage the rich COD content to perform atomistic simulations with MedeA.
